Can you share the configuration of the SIP trunk on your gateway?

You can configure those details under the sip-ua section or under voice class tenant.

Are you sure you are not confusing two different things here ? It's a SIP trunk and it is a PRI with 100 numbers ? What is that supposed to mean ? Are you porting from TDM to SIP ? Also, do they require the trunk to be registered or are the credentials for proxy auth ?

[Amod Joshi]

Dear Nipun,

Its a sip trunk with 10 channels and 100 DID’s. ITSP provided us the public ip, username password, domain name.

[R0g22]

You won't have CHANNELS per se for a SIP trunk. SIP trunk is nothing but a WAN/ISP IP link. The number of calls that you can route through that SIP trunk is dependent upon the bw for the link and the codecs in use. You can have as many DID's as you like but you need to take care that if all the DID's are making/receiving simultaneous calls, it should not over subscribe the trunk/IP/WAN link.

Hi,

There are some ITSP request to register each DDR in proxy server using E164. So for each DDR you will use the <credentials username 4XXXXXXX password 7 050F13022C55 realm 192.168.1.6>.
