[Sip-implementors] SIP INVITE authenticate response

2008-10-20 Thread Cynthia He
Hi all, As I mentioned in a previous email, which I got great help very fast from this list, we have a UA that connects a hardware radio device to an Asterisk PBX. When we receive an proxy authenticate challenge from asterisk, we tried (very hard :-) ) to calculate a response and send it b

If you are on the registrar side of things, then by being sufficiently liberal in what you accept you can make this work. If you examine the specified procedures that a registrar is to follow, then the only real dependence on callid and cseq is at the level of the binding of individual contacts

Thanks Paul, I'm actually on the other end of the deal. A customer is using a PBX that registers multiple AORs. It uses the same Call-ID for all the registrations which doesn't work out-of-the-box with our PBX. I'm just trying to get a grasp on what, if anything, their PBX is not doing incorrectly

Paul, Sorry, I still haven't got my hands around the proper terminology for SIP. It's sending out registrations for distinct AORs. Each registration has a distinct user in the To URI. Hope that clears it up. On Mon, Oct 20, 2008 at 9:29 AM, Paul Kyzivat <[EMAIL PROTECTED]> wrote: > > > Vadim Be
