Elastix, how to determine the number?

Question

Elastix

Good afternoon everyone!
On my elastix there is an extension (111), another asterisk is connected to it by trunk. Routing is configured on this asterisk (if the number is ours, then the call goes to our trunk).
On my side, I see incoming calls as SIP/111. Those. on my phones, the incoming call is defined as 111.
Is it possible to somehow see the actual number of the caller from the remote asterisk?

Answer 1

If on another asterisk connected to yours, the CID is substituted for outgoing ones, then nothing.
Dump the call and see what comes in INVITE in the FROM field.
If there is "sip:111" then check if the Remote-Party-ID field is there. If a normal CID (and not 111) is transmitted in this field, then write "trustrpid=yes" in your peer 111 properties.
