I have CME with one SIP trunk registered with ITSP, the trunk is authenticated with user and password.
- outgoing call works fine but not for incoming call for sip phones, debug show
error SIP/2.0 404 Not Found (the number does not exist is the prompt we listen)
- with SCCP/CIPC we have outgoing and incoming calls working fine.
I not sure if the problem is because the lines of SIP phones for CME appears as not registered. see screenshot
How can I avoid this issue with sip phones?
