Hello, I am having an issue with calls inbound to my UC 560.
The SIP provider suggests is may be a NAT setting.
They also suggest to "suppress" the first set (c=IN) in the code (below) since it is asking for a private IP:
v=0 o=CiscoSystemsSIP-GW-UserAgent 5653 7153 IN IP4 126.96.36.199 s=SIP Call i=(o=IN IP4 10.0.1.54) c=IN IP4 10.0.1.54 t=0 0 m=audio 54472 RTP/AVP 0 101 c=IN IP4 188.8.131.52 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20
Please advise. Thank you.
I am attaching the SIP logs.
