The info method is unofficial and non-standard. One of its limitations is that it *isn't* negotiated. The "official" ways are: - in the rtp media itself - rfc2833 in the media stream - kpml event package (draft-ietf-sipping-kpml-08, which is done except for dependency, on gruu I think.) In

[Sip-implementors] Mechanism to generate 'nonce' in SIP authentication

[Sip-implementors] DTMF tones

2009-04-07 Thread Peter Nijhuis
Sending dtmf tones over sip can be done in 2 ways, SIP INFO or RFC2833. Using RFC2833 is negotiated in the SDP message as Media Attribute (a): rtpmap:101 telephone-event/8000. In SDP is negotiated if this media attribute is used or not, but when sending dtmf as SIP INFO there is no negotiation,

2009-04-07 Thread Rahul A. Jadhav
You should always see 200 OK retransmissions in this case, until the UAS receives the ACK or the transaction times out. On receiving BYE, the transaction layer would treat it as a different transaction altogether and wont try to relate it in anyway to the INVITE transaction. Thus transaction layer

[Sip-implementors] Handling retransmission for 200 OK- when BYE received, before ACK for INVITE

2009-04-07 Thread sudhagar
Hi, I would like to know, what should be the behavior of UAS, when receiving a BYE for an INVITE transaction, to which 200 OK has already been sent, but instead of UAC sending an ACK sends a BYE after receiving 200 OK for INVITE. I currently see that our UAS responds with a 200 OK to t
