Good day! We have a UC500 series router with CME.
Also we have a plenty PBX and CUCM cluster in our environment
We use both SCCP and SIP IP phones, but SIP phones are 3d-party phones.
I have registered 2 SIP 3d-party phones
When I place call from outside, for example from one of PBX, the call sucessful,
but if I try to call from one 3d-party SIP-phone to another, I have an error 404 NOT FOUND.
Local calls from SIP to SCCP phones are sucessful too.
Here is a simple scheme:
[0388] +---------SIPphone1[1051]
PBX ----------CME--------SIPphone2[1052]
+---------SCCPphone[1006]
Voice part of router config - in attached file
