Re: [Sip-implementors] re-transmission timer for UAC transaction (INVITE) failed

Re: [Sip-implementors] Can PRACK be challenged??

after receiving the PRACK.If it so, then the PRACK with credentials will not have the matching RPR as the RPR will get removed when first PRACK is received. Is this not contradicting with the above statement(i.e., statement from 3262 section 3)?? Thanks, Praveen Dandin Paul Kyzivat [EMAIL

[Sip-implementors] Is session-expires be sent in 2xx response even though UAS doesnt support session timer?

. Also the draft says that the session timer extension has the property that it works even when only one UA in a dialog supports it. So what should be the behaviour of UAC (which is supporting session timers) in case UAS does not support session timers?. Thanks, Praveen Dandin

OK responses must follow the Vias listed in INVITE, they cannot be retransmitted over different proxies. On 10/17/2007 2:12 AM, praveen dandin wrote: Hi, Consider the following scenario ( proxies between UAC and UAS are not shown) UAC UAS INVITE
