mainly looking for RFC that specify how to implement answer supervision
and pulse metering. Thanks a lot for your time.

change

so you can leave out 101 our put in like 97 referring to the same

Hello SIP experts,
I have a question about codec negotiation when a UA receives re-INVITE
with no SDP.
Lets say, the codec negotiation between UA and Proxy ended up with G711
and RFC 2833 (m=audio 60146 RTP/AVP 0 101). However after the call gets
established, if the proxy sends re-INVITE
Hello SIP experts,
Is the following media description in SDP valid:
m=image 30032 udptl 0
I tried to figure out what is a valid "media format" for "media type"
image. The closest I can get to for an answer is in RFC 6466. But even
this RFC does not explicitly specify what the valid media

I would like to know if there are any RFCs that deal with emergency call
handling in SIP. I have been referred to

But this is a draft. Has this been made into RFC. If so, please
provide me with the RFC

Paul,
Thanks for the response
Hello,
We have a analog to SIP gateway that collects digits dialed from POTS lines and
initiates the SIP call by sending INVITE to a proxy server.
How can a user agent detect that it is calling itself in SIP? Either from
incoming INVITE or from a INVITE response?
We have to implement a
Hello,
Does anyone know which RFC to use to implement SIP based pay phones?
