[SR-Users] Issue with UAC restore_mode when restore_dlg is enabled

[jenus at cyberchaos.nl]

Hello,

I'm running into a issue with restore_mode auto when i enable 
restore_dlg in the uac module. I have a feature where i reroute calls 
for a subscriber when it is offline. When routing calls to the 
subscriber i check the exit status of "lookup("location")" and re-route 
the call. This works fine. It seems to fail when i hit the failure route 
(subscriber has a usrloc entry but does not respond). In the failure 
route i append_branch and reroute the call.

The rerouting works fine, but when i receive the ACK on the 200OK on the 
re-routed call the "restore" feature seems to fail and i end up with a 
header like:

To: 
<sip:+<null>@voip-dev.domain.nl>;tag=5B8ABC8A-5C6ABE83000EBF35-AB202700
in the ACK.

If i disable restore_dlg feature from the UAC module it adds the vsf/vst 
to the Record-Route header and all works fine.

Do i need to do something special when i create a new branch and use the 
restore_dlg feature?


Thanks,
