Noga, have you resolved this? Looking at your pcap trace I don't see anything wrong there. Here's what I think had happened: - The INVITE forked, and both 180 responses wants 100rel. - PJSIP sent the first PRACK to the first call-leg (the first 180 response). It sent the PRACK to the URI in the Contact of the 180 response, as you expected. - But this PRACK was responded with 481, hence terminating the dialog. cheers Benny On Wed, Feb 11, 2009 at 1:14 PM, Noga Yehudai <nogab@juniper.net> wrote: > It should deliver the next request to the URI from the contact – which is > the sbc uri. > > > > Noga. > > > ------------------------------ > > *From:* pjsip-bounces@lists.pjsip.org [mailto: > pjsip-bounces@lists.pjsip.org] *On Behalf Of *Gang Liu > *Sent:* Thursday, February 05, 2009 3:29 PM > > *To:* pjsip list > *Subject:* Re: [pjsip] PRACK and local outbound proxy > > > > Pls consider, how can pjsua know where callee is if your SBC hide the > callee contact. > > > > > > On Thu, Feb 5, 2009 at 8:47 PM, Noga Yehudai <nogab@juniper.net> wrote: > > Inline > > > ------------------------------ > > *From:* pjsip-bounces@lists.pjsip.org [mailto: > pjsip-bounces@lists.pjsip.org] *On Behalf Of *Gang Liu > *Sent:* Thursday, February 05, 2009 12:58 PM > > > *To:* pjsip list > *Subject:* Re: [pjsip] PRACK and local outbound proxy > > > > inline. > > On Thu, Feb 5, 2009 at 6:42 PM, Noga Yehudai <nogab@juniper.net> wrote: > > New requests within the dialog will usually go where stated in contact > header of the previous response or as you said using the record route URI. > > The outbound proxy configuration claims that any request will pass through > the proxy, regardless of the contact/RR URIs. > > This isn't true for RFC 3261. > > [Noga] you are right, only apply to req' uri. > > I use SBC instead of proxy, and I can't make it add record route, > therefore there will be no record route at all.

I use SBC instead of proxy, and I can't make it add record

I didn't check pjsip source code to check how PRACK handle

BTW, any Record-Route Header added into 200 OK respond?

Isn't that the point of local outbound proxy configuration - to

Enable record route at your proxy and try again.

180 ring from proxy don't include Record-Route Header.

Hi,

I found a problem when using Pjsua with -use-100rel and

When using outbound proxy with PRACK, the PRACK will be sent

Do you have any idea how to overcome this issue? Is it a known

I attached the capture of the call you can use Wireshark to view

Thanks,

Hi, I didn't solve it. The Invite wasn't forked. The reason that you see 2 call-IDs is that I use SBC instead of proxy, and the SBC acts as B2BUA. The SBC IP is 60.101.201.1 it manages 2 legs of the call independently (meaning different dialogs). The capture shows the UAC side.

The outbound proxy configuration claims that any request will pass through the proxy, regardless of the contact/RR URIs. This isn't true for RFC 3261. [Noga] you are right, only apply to req' uri. I use SBC instead of proxy, and I can't make it add record route, therefore there will be no record route at all. But it does put its own URI in the contact header - and this was ignored by pjsip as well. I don't think it is SBC. It didn't change contact of 180 respond. [Noga] it does change the contact; please see line 5 in cap file as opposed to line 4.
