Call Limit Time

Now we offer you two types of call duration limit, you can choose “Single Call Duration Limit” or “Call Duration Limitation” to control your calling time.

This will limit the time of each call. First you need to switch “Enable” on, then you can set “Step” and “Single Call Duration Limitation” any digits you want. When you make a call through this port, your calling time will be limited.

Single Call Duration Limitation：If your calling time exceeds the set value, the system will hang up the call. Multiplying the step size by a single call time is to allow a single call duration.

Figure 3-8-3 Single Settings

Call Duration Limitation：This will limit your total calling time of this port. If remain time is 0, it will not send calls through this port.

Figure 3-8-4 Call Duration Limitation Settings

The same as the algorithm for the single call duration limit, the total call time of the port cannot exceed the product of the “Step” and the “Call Duration Limitation”. The Minimum Billing Time value must be less than the step size.

You can set a value for the Alarm Threshold. When the remaining call duration of the port reaches the set value, the gateway will send alarm info to the designated phone.

You can also turn on enable auto reset, which can be selected from one day, one week or one month. After the automatic reset time is reached, the remaining call duration is reset to the set total call duration.

Figure 3-8-5 Auto Reset Settings

Table 3-8-1 Description of Call Duration Limit Settings

Options	Definition
Step	The value range of the step length is 1-999s. Multiplying the step size by a single call time is to allow a single call duration.
Enable Single Call Duration Limit	The value of the single call duration limit, ranging from 1-999999. The step size multiplied by the single talk time is the single call duration.
Enable Call Duration Limitation	The value of the total call duration limit, in the range of 1-999999. The step size multiplied by the total talk time is the total call duration.
Minimum Charging Time	After a period of conversation, the operator starts billing, in seconds. This value must be less than the step size.
Alarm Threshold	The threshold for the duration of the call. When the duration of the call is equal or less than this value, the gateway will send an alert message to the specified phone number via SMS (only once before the total call duration is reset). This value must be less than the call duration limit.
Alarm Phone Number	User will received alarm message from the gateway when receiving alarm phone number.
Alarm Description	The alarm port information description sends the alarm information to the user’s phone.
Remaining call duration	Multiplying this value by the step size is the remaining call duration.

Options	Definition
Name	A name is easier to understand, only for reference, does not participate in SIP authentication.
Username	Register name in your SIP server.
Password	Authenticating with the gateway and characters are allowed.
Registration	Whether the terminal registers with the gateway or the gateway registers with the terminal. None — Not registering; Server — When register as this type, it means the gateway acts as a SIP server, and SIP endpoints register to the gateway; Client — When register as this type, it means the gateway acts as a client, and the endpoint should be register to a SIP server.
Hostname or IP Address	IP address or hostname of the endpoint or ‘dynamic’ if the endpoint has a dynamic IP address. This will require registration. Notice: If you entered the domain name and changed the DNS, you must restart asterisk.
Transport	This sets the possible transport types for outgoing. Order of usage, when the respective transport protocols are enabled, is UDP, TCP, TLS. The first enabled transport type is only used for outbound messages until a Registration takes place. During the peer registration the transport type may change to another supported type if the peer requests so.

4.1.2 Add New IAX2 Endpoint

You can click  button to add a new IAX2 endpoint and if you want to modify existed endpoints, you can click  button.

There are three registration types: None, Server or Client.

You can configure as follows:

If you set up an IAx2 endpoint by registration “None” to a server, then you can’t register other IAX2 endpoints to this server, just authenticate the username and password.

Figure 4-1-8 None Registration

  

For convenience, you can choose registration by “Server”, thus your gateway just work as a server.

Figure 4-1-9 Server Registration

Also you can choose registration by “Client”, it will work as a Client.

Figure 4-1-10 Client Registration

Table 4-1-6 Definition of IAX2 Options

Options	Definition
Name	A name which is able to read by human. And it’s only used for user’s reference.
Username	The endpoint will use username to authenticate with the gateway.
Password	The endpoint will use password to authenticate with the gateway.
Registration	Whether this endpoint will register to this gateway or this gateway to the endpoint. None — Not registering; Endpoint registers with this gateway — When register as this type, it means the gateway acts as a IAX2 server, and IAX2 endpoints register to the gateway; This gateway registers with the endpoint — When register as this type, it means the gateway acts as a IAX2 client, and the endpoint should be register to a IAX2 server;
Hostname or IP Address	IP address or hostname of the endpoint or ‘dynamic’ if the endpoint has a dynamic IP address. This will require registration. Notice: If you entered the domain name and changed the DNS, you must restart asterisk.
Auth	There are three authentication methods that are supported: md5, plaintext and rsa. The least secure is “plaintext”, which sends passwords clear text across the net. Uses a challenge/response md5 sum arrangement, but still requires both ends have plain text access to the secret. “rsa” allows unidirectional secret knowledge through public/private keys.
Transfer	Disable or not IAX2 native transfer .
Trunk	Use IAX2 trunking with this host.

Figure 4-3-2 NAT Settings

Table 4-3-2 Definition of NAT Settings Options

Options	Definition
Local Network	Format:192.168.0.0/255.255.0.0 or 172.16.0.0./12. A list of IP address or IP ranges which are located inside a NAT network. This gateway will replace the internal IP address in SIP and SDP messages with the external IP address when a NAT exists between the gateway and other endpoints.
Local Network List	Add local IP address list.
Subscribe Network Change Event	Through the use of the test_stun_monitor module, the gateway has the ability to detect when the perceived external network address has changed. When the stun_monitor is installed and configured, chan_sip will renew all outbound registrations when the monitor detects any sort of network change has occurred. By default this option is enabled, but res_stun_monitor only takes effect once. If res_stun_monitor is enabled and you don’t want changes on the network to cause an outbound registration, use the option below to disable this feature.
Match External Address Locally	Only substitute the extern address or extern host setting if it matches.
Dynamic Exclude Static	Dynamic hosts are not allowed to register with the static host’s IP address, which will avoid the same IP registration error.
Externally Mapped TCP Port	The externally mapped TCP port, when the gateway is behind a static NAT or PAT.
External Address	The external address (and optional TCP port) of the NAT. External Address = hostname[:port]. Specifies a static address[:port] to be used in SIP and SDP messages. Examples: External Address = 12.34.56.78 External Address = 12.34.56.78:9900.
Hostname Refresh Interval	How often to perform a hostname lookup. This can be useful when your NAT device lets you choose the port mapping, but the IP address is dynamic. Beware, you might suffer from service disruption when the name server resolution fails.

Parsing and compatibility

Figure 4-3-4 Parsing and Compatibility

Table 4-3-4 Instruction of Parsing and Compatibility

Options	Definition
Strict RFC Interpretation	Check header tags，character conversion in URIs, and multiline headers for strict SIP compatibility(default is yes).
Send Compact Headers	Send compact SIP headers.
SDP Owner	Allows you to change the username filed in the SDP owner string. This filed MUST NOT contain spaces.
Disallowed SIP Methods	When a dialog is started with another SIP endpoint, the other endpoint should include an Allow header telling us what SIP methods the endpoint implements. However, some endpoints either do not include an Allow header or lie about what methods they implement. In the former case, the gateway makes the assumption that the endpoint supports all known SIP methods. If you know that your SIP endpoint does not provide support for a specific method, then you may provide a list of methods that your endpoint does not implement in the disallowed methods option. Note that if your endpoint is truthful with its Allow header, then there is no need to set this option.
Shrink Caller ID	The Shrink Caller Id function removes ‘(‘, ‘ ‘, ‘)’, non-trailing ‘.’, and ‘-‘ not in square brackets. For example, the caller id value 555.5555 becomes 5555555 when this option is enabled. By default this option is on.
Caller ID	Default：SIP From and Number. For example：When selecting SIP From, Name is Peter and Number is 402. The From mode is: “Peter”<sip:[email protected];transport=UDP>;tag=bd481672.
Callee ID	Default: EXTEN For example: When selecting SIP To, Name is Jason and Number is 401. The mode is: “Jason”<sip:[email protected];transport=UDP>.
Maximum Registration Expiry	Maximum allowed time of incoming registrations and subscriptions (seconds).
Minimum Registration Expiry	Minimum length of registrations/subscriptions (default 60).
Default Registration Expiry	Default length of incoming/outgoing registration.
Registration Timeout	How often, in seconds, to retry registration calls. Default 20 seconds.
Number of Registration	Number of registration attempts before we give up.

Security

Figure 4-3-5 Security Settings

Table 4-3-5 Instruction of Security

Options	Definition
Match Auth Username	If available, match user entry using the ‘username’ field from the authentication line instead of the ‘from’ field.
Realm	Realm for digest authentication. All realms must be globally unique according to the RFC3261 standard and can generally be set to hostname or domain name.
Use Domain as Realm	Use the domain from the SIP Domains setting as the realm.
Always Auth Reject	When an INVITE or REGISTER request is rejected for any reason, the same reason is always used, the username is legal but the password is incorrect. It does not tell the requester whether there is this user or peer, which will reduce the possibility of the attacker scanning the SIP account. This parameter is enabled by default.
Authenticate Options Requests	Enabling this option will authenticate OPTIONS requests just like INVITE requests are. By default this option is disabled.
Allow Guest Calling	Allow or reject customer calls (default yes, allowed). If your gateway is connected to the Internet and allows customers to call, you want to check which services are available to everyone, by enabling them in the default context.

Options	Definition
Bind Port	Bind port and bindaddr may be specified
Enable IAXCompat	Set Iaxcompat to yes if you need to use a tiered switch, or if some of the latency may occur when performing a lookup in a dial plan, otherwise enabling it will result in a small performance conflict.
Enable Nochecksums	Disable UDP checksums (if Nochecksums is set, then Nochecksums will be calculated/checked on systems supporting this feature).
ADIS	ADSI (Analog Display Services Interface) can be enabled if you have (or may have) ADSI compatible CPE equipment.
SRV Lookup	Whether or not to perform an SRV lookup on outbound calls.
AMA Flags	You may specify a global default AMA flag for IAX internal calls. These flags are used in the generation of call detail records.
Auto Kill	If we don’t get ACK to our NEW within 2000ms, and Auto Kill is set to yes, then we cancel the whole thing (that’s enough time for one retransmission only). This is used to keep things from stalling for a long time for a host that is not available, However, this function is not friendly in the case of poor connection status.
Language	You may specify a global default language for users. This can be specified also on a per-user basis. If you ignore this item, it will use the default English language.
Account Code	You may specify a default account for Call Detail Records (CDRs) in addition to specifying on a per-user basis.

Jitter Buffer Settings

Figure 4-4-4 Jitter Buffer

Table 4-4-4 Instruction of Jitter Buffer

Options	Definition
Jitter Buffer	Whether to set a global buffer should be enabled by an unstable network environment, generally you do not need. Because the terminal device buffers the jitter processing. The default is “no”.
Force Jitter Buffer	In the ideal world, when we bridge VoIP channels we don’t want to jitter buffering on the switch, since the endpoints can each handle this. However, some endpoints may have poor jitter buffers themselves, so this option will force to always jitter buffer, even in this case. The default is “no”.
Max Jitter Buffers	A maximum size for the jitter buffer.
Resyncthreshold	When the jitter buffer notices a significant change in delay that continues over a few frames, it will resync, assuming that the change in delay was caused by a timestamping mix-up. The threshold for noticing a change in delay is measured as twice the measured jitter plus this resync threshold. Resyncing can be disabled by setting this parameter to -1.
Max Jitter Interps	The maximum number of interpolation frames the jitter buffer should return in a row
Jitter Target Extra	Number of milliseconds by which the new jitter buffer will pad its size. The default is 40, so without modification, the new jitter buffer will set its size to the jitter value plus 40 milliseconds. Increasing this value may help if your network normally has low jitter, but occasionally has spikes.

Misc Settings

Figure 4-4-5 Misc Settings

Table 4-4-5 Instruction of Misc Settings

Options	Definition
IAX Thread Count	Establishes the number of IAX helper threads to handle I/O
IAX2 Max Thread Count	Establishes the number of extra dynamic threads that may be spawned to handle I/O.
Max Call Number	The ‘Max Call Numbers’ option limits the amount of call numbers allowed for each individual remote IP address. Once an IP address reaches its call number limit, no more new connections are allowed until the previous ones close. This option can be used in a peer definition as well, but only takes effect for the IP of a dynamic peer after it completes registration.
MaxCallNumbers_ Nonvalidated	The ‘MaxCallNumbers_Nonvalidated’ is used to set the combined number of call numbers that can be allocated for connections where call token validation has been disabled. Unlike the ‘ Max Call Number ‘ option, this limit is not separate for each individual IP address. Any connection resulting in a non-call token validated call number being allocated contributes to this limit. For use cases, see the call token user guide. This option’s default value of 8192 should be sufficient in most cases.

4.5 SIP Account Security

The SIP account security module greatly enhances the security of the system. The wireless gateway supports TLS encrypted calls (sip), which requires sip phone support.

Figure 4-5-1 SIP Account Security

You need to understand its rules when using TLS. The following table shows the setting parameters of TLS.

Table 4-5-1 Parameters of TLS settings

Options	Definition
TLS Enable	Enable or disable DTLS-SRTP support.
TLS Verify Server	If set it off, there is no need to verify the server certificate when the client is operating. If you do not have a server CA certificate, you can disable authentication to connect without the need for a TLS CA file.
Port	TLS port SIP registration, default port 5061.
TLS Client Method	Values include tlsv1, sslv3, sslv2, which specify the protocol for the outbound client connection. The default is sslv2.

Enter the key name, IP address, organization and password in the above settings to create a ca certificate. After mutual authentication between the client and the server, it can be accessed with a certificate.

We need to do a few basic steps:

1. Your asterisk server requires an authentication. We must create or add a certificate on the asterisk server. We need to create a digital key for our server, the server key is the key.pem file, and the certificate request is request.pem.
2. Add some configuration settings to the sip.conf file.
3. Configure the client to use TLS.

In the Advance Routing Rule Settings, you can set the function of the dial Patterns、Time Patterns、Calling, Forward, Delay and Failover.

Table 5-1-2 Description of Advanced Routing Rule

Options	Definition
Dial Patterns that will use this Route	A Dial Pattern is a unique set of digits that will select this route and send the call to the designated trunks. If a dialed pattern matches this route, no subsequent routes will be tried. If Time Groups are enabled, subsequent routes will be checked for matches outside of the designated time(s). Rules: X matches any digit from 0-9 Z matches any digit from 1-9 N matches any digit from 2-9 [1237-9] matches any digit in the brackets (for example: 1,2,3,7,8,9). Wildcard: matches one or more dialed digits. Prepend: Digits to prepend to a successful match. If the dialed number matches the patterns specified by the subsequent columns, then this will be prepended before sending to the trunks. Prefix: Prefix to remove on a successful match. The dialed number is compared to this and the subsequent columns for a match. Upon a match, this prefix is removed from the dialed number before sending it to the trunks. Match pattern: The dialed number will be compared against the prefix + this match pattern. Upon a match, the match pattern portion of the dialed number will be sent to the trunks. CallerID: If CallerID is supplied, the dialed number will only match the prefix + match pattern if the CallerID has been transmitted matches this. When extensions make outbound calls, the CallerID will be their extension number and NOT their Outbound CID. The above special matching sequences can be used for CallerID matching similar to other number matches.
Set the Caller ID Name to	What caller ID name would you like to set before sending this call to the endpoint.
Set the Caller ID Number to	What caller ID number would you like to set before sending this call to the endpoint.
Forward Number	This number will be sent to target PBX or SIP Server as a DID number for inbound rule settings.
Custom Context	Custom the context of dialing rules.
Random Delay	Randomly obtain any value within the threshold interval.
Failover Call Through Number	The gateway will attempt to send the call out each of these in the order you specify.

5.2 Groups

Sometimes you want to make a call through one port, but you don’t know if it is available, so you have to check which port is free. That would be troublesome. But with our product, you don’t need to worry about it. You can combine many Port or SIP to groups. Then if you want to make a call, it will find available port automatically.

For the “Ascending” policy, if 2 or more port members are selected, it will use the first available port to call/access the call. In this case, if the gsm-1.1 is available, it will always use the gsm-1.1 call, otherwise, it will use gsm-1.2, and so on.

Figure 5-2-1 Routing Groups

5.3 Batch Creating rules

This page can generate multiple routing rules at the same time.
