Andreas is 100% right. Please ask them an explanation regarding why you should
remove your record-route headers. Maybe what they don't like is having
"127.0.0.1" in the rr header (which is 100% valid).

I can't believe that a sbc can't hable rr headers.


btw, I agree with Andreas, you'd better change your provider. But I'd like to
know what their explanation is first.


cheers,

Jon
