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 68.164.107.234
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 68.164.107.234
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=ptime:20
Please advise. Thank you.
