Table 4-3-2 NAT Settings

Options	Description
Local Network	Format: 192.168.0.0/255.255.0.0 or 172.16.0.0/12. A list of IP addresses or IP ranges within the NAT’s network. When NAT exists between the gateway and the peer device, the gateway will replace the IP address in the SIP and SDP messages with an extended IP address.
Local Network List	Added the list of local IP addresses.
Subscription Network Change Time	When the external network address changes, the gateway can detect the change by using the test_stun_monitor module. When the stun_monitor is installed and configured, the chan_sip will update all outgoing registrations when the monitor detects any form of network change. This option is enabled by default, but the res_stun_monitor can only take effect once. If res_stun_monitor is enabled and you do not want changes on the network to generate outbound registrations, use the options below to disable this feature.
Local Match External Address	If the match is successful, only the external address or domain name is replaced.
Dynamic and static selection	Dynamic hosts are not allowed to register with the IP address of the static host. This will avoid the error of registering with the same IP.
External TCP Port Mapping	When the gateway is behind a static NAT or PAT, the TCP port is mapped externally.
External IP Address	NAT external IP address (and optional TCP port) External IP address = hostname [: port number] This format defines a fixed address for SIP and SDP information transmission. For example: external IP address = 12.34.56.78 external IP address = 12.34.56.78:9900
External Host Name	External hostname (and optional TCP port) for NAT
Host Name Refresh Interval	How often to perform a hostname lookup. You can also configure a domain name. The gateway will perform a DNS query. This method is not recommend. Try to use IP and configure externip.

Strict RFC parsing	Open the tag value detection in the message, URls and multi-line formatting header information Chinese standard character conversion and other strict SIP compatibility issues (default is yes).
Send compact head	Sends a compact SIP message header.
SDP Owner	Allows you to change the domain of the SDP username©. This field cannot contain spaces.
SIP method not allowed	When talking back to other SIP peers, then the other peers should include an Allow header to tell us the implementation of the SIP method. However, some peers do not include the Allow header or fake the methods they implement. In such a 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 particular method, then you may want to provide a list of methods that the peer does not implement disallowed_methods. Note: If your opposite end is real, then there is no need to set this item.
Shrink caller ID	This function can remove ‘(‘, ”, ‘)’, non-trailing ‘, ‘, and ‘_’ not in square brackets. For example, when this option is enabled, the value of caller ID changes from 555.5555 to 5555555. The default is enabled.
Maximum Registration Timeout	The maximum time allowed for incoming registration and subscription, in seconds.
Minimum Registration Timeout	The minimum length of registration and subscription, the default is 60.
Default Registration Timeout	The default inbound and outbound registration length.
Registration Timeout	How long does it take to re-register an extension? The default is 20 seconds.
Number of Registration Attempts	The number of registration attempts before abandoning registration.

4.4.3 Security and Media

Figure 4-4-3 Security and Media

Table 4-4-5 Security Setting Help

Options	Description
Match Authentication User Name	If available, use the username field of the authentication line to match the username instead of using the username field.
Domain	For certified realms, all domains must remain globally unique according to RFC3261 criteria. Generally, it can be set to host name or domain name.
Use a domain name as a domain	Use the SIP domain as the boundary for the domain.
Maintain Validation Decisive	When an INVITE or REGISTER request is rejected for any reason, the same reason is always used, the user name is valid but the password is incorrect. It will not tell the requester whether there is this user or peer, which will reduce the possibility of attackers scanning SIP accounts. This parameter is enabled by default.
Verify OPTIONS request	Turning this parameter on will cause the OPTIONS request to take effect just like an INVITE request. This parameter is turned off by default.
Allow customer calls	Allow or deny client calls (on by default, allow). If your gateway is connected to an external network and allows customers to call, you want to check what services are available to everyone and turn on in the default context.

Table 4-4-6 Media Settings

Options	Description
Early Media	Some SDN connections send empty media frames or process state before the phone rings. The SIP tunnel will send 183 representation as early null media. The user therefore receives no ringing signal. Set this to “yes” to organize additional media before receiving the call process (the SIP tunnel will not send the 183 session process for other early media). The default is ‘yes ‘. Confirm that the configuration file of SIP peer is set to progressinband = never. In order to’ no answer’ function be applied, you need to execute progress() before running app.
TOS for SIP packets	Sets the service type for SIP packets.
TOS for RTP packets	Set the service type for RTP packets.

4.5 Sip Account Security

The mock gateway supports TLS protocol encryption. It can work in TLS server mode, generate the session key used in the secure connection process, or register as a client and upload the key file provided by the server.

Description

Calling/called number filtering and transformation

The dial pattern is 1 unique set of digits that will route and send the call to the designated trunk. If the dialing pattern matches this route, the other routing rules will not match. If the time mode is enabled, then the matching route will be checked to see if it matches any number in 0-9, z in 1-9, n in 1-9, any number in 2-9 [1237-9], matches any number in brackets <e.g. 1,2,3,7,8,9> * matches one or more number Prepend <prefix>: the number to add if the pattern match succeeds. If the dialed number matches the pattern specified in the subsequent column, the number is added before being sent to the relay. Prefix <prefix>: removed when the pattern matches successfully. The dialed number is matched against the pattern specified in the subsequent columns, and once a match is successful, the prefix is removed from the number before it is sent to the relay. Match Pattern <matching pattern>: The dialed numbers are compared GG1 the ‘prefix + the number of this matching pattern. Once the match is successful, the matching pattern portion of the dial is sent to the relay. SDfR <number of digits deleted from the right>: number of digits deleted from the right. If this value exceeds the length of the current number, the entire number will be deleted. RDfR <number of reserved digits from right>: number of reserved digits from right. StA <add suffix>: This number is added from the right end of the current number. Caller Name <caller display name>: set the caller name you like before sending this call to the terminal, allowing the use of local languages, such as Chinese and Latin.

5.2 Group

Sometimes you want to make a call from a certain port, but you don’t know if it is available, so you also have to check which port is available. This will be troublesome. But with our products, you no longer need to worry about this problem. You can add multiple ports or SIPs to a group. When you want to make a call, it will automatically look for available ports.

Figure 5-2-1 Group Rules

Table 5-2-1 Routing group description

Options	Description
Group Description	The name of the route, which describes the type of call route, such as sip1TOport1 or port1TOsip2.
