[Sip-implementors] Authentication through WDS.
Hi All, We are planning to integrate authentication mechanism in SIP with Windows Active Directory (WDS). Such that, when an UA sends its digest response for incoming 401/407, the proxy in some mechanism has to contact the active directory to confirm the authentication of the user. But SIP supports authentication through digest and we are not sure whether the same is supported by WDS and we also learnt that WDS will not give the password but will only conform the correctness of the password given. It will be helpful if anyone can through some light on how this can be achieved.

Re: [Sip-implementors] RE-INVITE Problem [packet capture inside]
From: Manjunath Warad <[EMAIL PROTECTED]>
I have strong doubt on the SDP that is exchanged in 200 of
Re-INVITE. Answerer has added other media formats that he supports and I
don't think offerer would support those and hence offerer could be releasing
the call by sending ACK and BYE.
Why do you have doubt? Read RFC 3264 ("An Offer/Answer Model with the
Session Description Protocol (SDP)"), section 8 ("Modifying the
Session"), subsection 8.3 ("Modifying a Media Stream"), subsection
8.3.2 ("Changing the Set of Media Formats"):
The list of media formats used in the session MAY be changed. To do
this, the offerer creates a new media description, with the list of
media formats in the "m=" line different from the corresponding media
stream in the previous SDP. This list MAY include new formats, and
MAY remove formats present from the previous SDP. However, in the
case of RTP, the mapping from a particular dynamic payload type
number to a particular codec within that media stream MUST NOT change
for the duration of a session.

Re: [Sip-implementors] few queries regarding SDP implementation for multiple bit rates for g.722 codec
(Query 1) I think you can specify multiple a= lines in SDP m=audio 9292 RTP/AVP 9 a=rtpmap:9 G722/48000 a=rtpmap:9 G722/56000 a=rtpmap:9 G722/64000 (Query 2) m=audio 9292 RTP/AVP 9 0 a=rtpmap:9 G722/64000 a=rtpmap:0 PCMU/8000 m=audio 9296 RTP/AVP 9 18 a=rtpmap:9 G722/56000 a=rtpmap:18 G729/8000 m=audio 9298 RTP/AVP 9 a=rtpmap:9 G722/48000 (Query 3) Honestly dont know which one is better in network.
