I tried to do a "no ip nat service sip tcp port 5060" command. This removes
the "482 Loop Detected Error" and allows the client ip phone to register.
However, outgoing calls fail, because the SBC on the other end responds with
an "403" error. Apparently, the header being submitted is not acceptable.
Anybody come accros this before?
I think that at least in CBAC, IOS 12.2 couldn't understand compact sip
messages. I don't know if this is still an issue, but you may try to
change your phone to not use compact headers.
