Hi all,
In the INVITE from my SIP provider to Asterisk i can see that the
Allow Header includes an INFO Method, but Asterisk replies a 200 OK
with an Allow Header without INFO Method. But in the RFC3261 (20.5)
you can read:
"All methods, including ACK and CANCEL, understood by the UA MUST be
included in the list of methods in the Allow header field, when
present. "
My SIP provider seems to refuse to send SIP INFO DTMF and releases the
call, because in 200 OK from * there is no INFO Method in the Allow
Header.
Is that correct.
thx
richard
