4.1 SIP Endpoint

On this page, the status information about the SIP account is displayed.

Figure 4-1-1 SIP Endpoints

Click the edit button to modify the corresponding SIP information.

4.1.1 Main Endpoint Settings

There are 3 kinds of registration types for choose on the VoxStack series analog gateways. You can choose “Anonymous, Endpoint registers with this gateway or This gateway registers with the endpoint”.

You can configure as follows:

If you set up a SIP endpoint by registration “None” to a server, then you can’t register other SIP endpoints to this server. (If you add other SIP endpoints, this will cause Out-band Routes and Trunks confused.)

Figure 4-1-2 Main Endpoint Settings

For convenience, we have designed a method that you can register your SIP endpoint to your gateway, thus your gateway just work as a server.

Figure 4-1-3 Main Endpoint Settings

When “Gateway is registered to the endpoint”, you need to fill in the username and password, and you can register multiple SIP endpoints to the server. Due to the difference in usernames and passwords, there will be no confusion between routing and Trunks.

Figure 4-1-4 Register to Server

Table 4-1-1 Definition of Endpoint Settings Options

Options	Definition
Name	A name which is able to read. And it’s only used for user’s reference.
Username	Username for authentication between the endpoint and the gateway.
Password	The password for authentication between the endpoint and the gateway, allowing letters.
Registration	None—Anonymous registration; Endpoint registers with this gateway—The gateway is used as a server, and the SIP endpoint is registered to the gateway; This gateway registers with the endpoint—The gateway is used as a client, and the SIP terminal needs to be registered on the server.
Domain name or IP address	IP address or domain name of the endpoint or ‘dynamic’ .（if the endpoint has a dynamic IP address.）This needs to register.
Alternate domain name or IP address	Same as above. After filling this, it is equivalent to that this account initiates registration to two domain names or IP addresses at the same time. When the account of the primary domain name or IP address expires, it will switch to the account of the alternate domain name or IP address
Transmission method	Set possible transmission types and order of use for outgoing transmissions. When you use various transport protocols: UDP, TCP, TLS, the transmission type enabled for the first time is only used for outgoing messages until registration occurs. If the endpoint requires another transmission type during the registration process, the first transmission type may be changed to another transmission type.
NAT Traversal	Issues related to NAT addresses when incoming SIP or media sessions.
VOS encryption	When the endpoint is a VOS server, the encryption item needs to be used, and the parameters need to be turned on at this time

SDP Version Header	By default, the gateway will add a session version number to the SDP packet and if the SDP version number is modified, it will only modify the SDP session. Turning off this option will force the gateway to ignore this SDP version number and treat all SDP data as new data. This is necessary for a device that sends non-standard SDP packets. It is turned on by default.
Allow Transfers	Whether or not to globally enable transfers. Choosing ‘no’ will disable all transfers (unless enabled in endpoints or users). Default is enabled.
Allow Promiscuous Redirection	Whether or not to allow 302 or REDIR to non-local SIP address. Notice: Redirecting to the local system will cause a loop call, which Asterisk does not support.
Maximum Forward	Setting for the SIP Max-Forwards header (loop prevention).

4.4.2 NAT Settings

Table 4-4-2 Definition of NAT Settings

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	Local IP address list that you added.
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 only takes effect once “res_stun_monitor” is configured. If “res_stun_monitor” is enabled and you wish to not generate all outbound registrations on a network change, use the option below to disable this feature.
Match External Address Locally	Only substitute the external address or domain name if it matches.
Dynamic and Static Selection	Dynamic hosts are not allowed to register with the IP address of static hosts. This will avoid registration errors with the same IP.
External TCP Port Mapping	When the gateway is behind a static NAT or PAT, the TCP port is externally mapped.
External IP Address	The external address of the NAT (and optional TCP port). External IP Address = hostname[:port] specifies a static address[:port] to be used in SIP and SDP messages. Examples: External IP Address = 12.34.56.78 External IP Address = 12.34.56.78:9900
External IP Hostname	The external hostname (and optional TCP port) of the NAT.
Hostname Refresh Interval	It will show how often to perform the hostname lookup. You can also configure a domain name. The gateway will perform a DNS query (This method is not recommended). Try to use IP and configure “externip”.

4.4.3 STUN Settings

Table 4-4-3 Definition of STUN Settings Options

Options	Definition

4.4.5 Parsing and Compatibility

Table 4-4-5 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 domain of the SDP username. £¨o=£© This filed MUST NOT contain spaces.
Disallowed SIP Methods	When speaking back to other SIP peers, the other peers should include an “Allow” header to tell us the implementation of the SIP method. However, some peers do not include “Allow” headers or forge the methods they implement. In this case, the gateway will assume that the peer supports all known SIP methods. If you know that your SIP peer does not provide support for a specific method, then you may need to provide a list of methods that the peer does not implement in “disallowed methods”. Notice: If your peer is real, then there is no need to set this option
Shrink Caller ID	The function can removes ‘(‘, ‘ ‘, ‘)’, non-trailing ‘.’, and ‘-‘ not in square brackets. For example, the caller id value 555.5555 becomes 5555555 when this option is enabled. Disabling this option results in no modification of the caller id value, which is necessary when the caller id represents something that must be preserved. By default this option is on.
Maximum Registration Expiry	Maximum allowable time for incoming registration and subscription (seconds).
Minimum Registration Expiry	The minimum length of registration and subscription (default 60).
Default Registration Expiry	Default length of incoming/outgoing registration.
Registration Timeout	How long will it take to re-register the extension (Default 20 seconds).
Number of Registration Attempts	Number of registration attempts before giving up.

4.4.6 Security and Media

Table 4-4-5 Instruction of Security and Media

Options	Definition
Match Auth Username	If available, use the user name field of the authentication line to match instead of using the user name of the user name field.
Realm	For authentication domains, all domains must be globally unique according to the RFC3261 standard. Generally can be set to host name or domain name.
Use Domain as Realm	Use the SIP domain as the boundary of the domain.
Always Auth Reject	When an “INVITE” or “REGISTER” request is rejected for any reason, the same reason will always be used. The username is legal but the password is incorrect. It does not tell the requester whether there is this “user” or “peer”, which reduces the possibility of an attacker scanning the SIP account (This option is set to ‘yes’ 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 (enabled by default, allowed). If your gateway is connected to an external network and allows customers to call, you want to check which services are provided for everyone and enable it in the default “context”.
Premature Media	Some SDN links will send empty media frames before the call is in ringing or progress state. The SIP channel will then send 183 indicating early media which will be empty – thus users get no ring signal. Setting this to “yes” will stop any medias before we have call progress (meaning the SIP channel will not send 183 Session Progress for early media). Default is ‘yes’. Also make sure that the “SIP peer” is configured with “progressinband=never”. In order for ‘no answer’ applications to work, you need to run the progress() application in the priority before the app.
TOS for SIP Packets	Sets type of service for SIP packets
TOS for RTP Packets	Sets type of service for RTP packets

4.5 Sip Account Security

This analog gateway support TLS protocol for encrypting calls. On the one hand, it can worked as TLS server, generate the session keys used for the secure connection. On the other hand, it also can be registered as a client, upload the key files provided by the server.

Figure 4-5-1 TLS settings

Table 4-5-1 Instruction of TLS

Options	Definition
TLS Enable	Enable or disable DTLS-SRTP support.
TLS Verify Server	Enable or disable TLS verify server (default is no).
Port	Specify the port for remote connection.

5. Routing

The gateway has a friendly user interface and very flexible settings. It supports up to 512 routing rules and each routing rule supports up to 100 pairs of calling/called number filtering and conversion operations. It supports DID function (the use of DID function: how to use the T1/E1 gateway DID function of China Telecom). The gateway supports trunk group and trunk priority management.

Figure 5-1-3 Advance Routing Rule

Table 5-1-2 Definition of Advanced Routing Rule

Options	Definition
CalleeID/callerID Manipulation	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). 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 (example: 1,2,3,7,8,9) *matches one or more digits Prepend<add prefix>: The number added when the pattern matches successfully. If the dialed number matches the pattern specified in the subsequent column, the number will be added before being sent to the trunk. Prefix: Removed when the pattern is matched successfully. The dialed number is matched with the pattern specified in the subsequent column. Once the match is successful, the prefix will be removed from the number before being sent to the trunk. Match Pattern: The dialed number will be compared with the number in the “prefix +” this matching pattern. Once the match is successful, the matched pattern part of the dial will be sent to the trunks. SDfR<Delete digits from the right>: The number of digits to be deleted from the right end of the number. If this value of this item exceeds the length of the current number, the entire number will be deleted. RDfR<Reserved digits from the right>: The reserved digits from the right. StA<Add Suffix>: Add this number from the right end of the current number. Caller Name <caller display name>: Set your favorite caller name before sending this call to the terminal, allowing the use of local languages, such as Chinese and Latin.
Time Patterns that will use this Route	Time mode setting of routing rules.
Forward Number	What destination number will you dial? This is very useful when you have a transfer call.
Failover Call Through Number	The gateway will attempt to send the call by the order you specified.

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 Ports or SIP to groups. Then if you want to make a call, it will find available port automatically.
