Two things come to mind: 1. Is your UA setup to use your openser as an outbound proxy? That tends to help with these kinds of problems. 2. You're using record-route in your openser.cfg. Check the Route and Record-Route headers in your SIP trace. It sounds like your UA may be ignoring them, which I've seen some UA's do. It's also quite likely that Asterisk screwed it up. 3. Try different combinations of UA or firmware for your UA. I've seen these kinds of problems with some of our equipment, and sometimes upgrading or downgrading firmware helps.

Hi all,

I'm trying to setup an openser using an asterisk as a pstn gw and voicemail server.

Everything seems to be working fine except when a call is redirected to voicemail by timeout (using failure_route).

In this situation, asterisk is asking for proxy auth to openser that redirects the request to the calling ua. But when the ua responds to openser, this latest sends the invitation to the destination ua and not to asterisk, as he should. I can't figure out a way of accomplishing this... any idea?

The sip trace diagram and the full openser.cfg are in attachment. The wrong invite is represented as "F19 INVITE" in the diagram...

Thanks, Edgar
