[OpenSIPS-Users] ACK never reach UAS

[Vlad Paiu]

Hello,

This is probably because your UAC does not send the Route headers. Can 
you confirm that the ACK that reaches OpenSIPS does not have any Route 
headers ?

As Jose said, you first have to instruct SIPP to first save the 
Record-Route headers, by having rrs="true" on your 200 Ok.
Second, you must tell SIPP to use them.  The ACK first line should be

     ACK [next_url] SIP/2.0

And also make sure you insert in the headers of the message the routes 
tag like
     [routes]

Recheck Jose's email for a perfect example of an SIPP ACK.

If you still can't fix the issue after doing all of the above, post your 
SIPP script and a SIP trace.

Regards,
Vlad
