Re: [Sip-implementors] Why is a stateless proxy needed?

I agree with Dale that SIP was designed in internet way wherein endpoints has to be intelligent. But the legacy telecom system believes in the network as intelligent with full of dump end-points from PSTN days, this leads to the building of SIP network full of B2BUA/stateful proxy. IMS architectu

I agree with Dale and Brett, sort of. Brett is right that the UAC is correct in ignoring the change in the 200. Dale is right that the UAS is wrong in sending different SDP in the 180 and 200. See http://www.ietf.org/id/draft-ietf-sipping-sip-offeranswer-13.txt Thanks, Paul On

Adding to what brett said... Why is it necessary to have a separate null address for IPv6? Null is null. Won't an IPv4 null address do? Even if your node doesn't support IPv4, I would think it could support a *null* IPv4. Thanks, Paul On 2/7/2011 7:09 AM, Brett Tate wrote: >> Wh

I would argue for the opposite convention: The URI should contain the real domain name, since "everything in SIP is encoded in UTF-8". Only at the point of resolving the domain name into destination addresses (the RFC 3263 process) would I translate "blåbärsmjölk.se" into "xn--blbrsmjlk-x2aj4s

Hello, I have a short question about the SDP rtpmap attribute (I hope, SDP-specific questions are also allowed here?): What characters are allowed in the encoding name? The BNF in RFC4566 only states that attribute values can take a "byte-string", but surely this can not be valid for the encoding
