Turning on sip debug using "sip set debug on" and verbosity using "core set debug 9" would give you more information about each packet (including where it is from) and what was actually matched based on it.

Thanks again for the hint.
Here is the output from asterisk.

The call is coming on Audocodes gateway from: pstn-4444

But asterisk display:
Found peer 'pstn-9998' for '7804715665' from 10.10.0.8:5060

Why not loolking up "pstn-4444" in sip.conf?
