A SIP trunk is used to create a virtual communication channel between two SIP servers. It can be two Axxon PSIM SIP servers, or the Axxon PSIM SIP server and a third-party SIP server.
Before you start configuring the SIP trunk, it is necessary to add to Axxon PSIM the SIP-devices of a third-party server based on the same SIP-terminal on which the SIP trunk will be added (see Configuring SIP-devices of the Axxon PSIM's SIP server).
In the following description of the SIP trunk configuration procedure, the connection between the Axxon PSIM SIP server and a third-party SIP server is used as an example.
The SIP trunk is configured as follows:
Click the Apply button.
Note
After you click the Apply button, the specified settings will be sent to the second server, and the registration will be received from it, that is, the connection will be updated. Then, the connection will be updated every 10 minutes. You can change this time interval using the ClientExpires key (see Registry keys reference guide).
The SIP trunk is configured.
Attention!
To ensure the SIP trunk operation, it is necessary that similar settings are made on the server, with which the communication should be set.
