[Spce-user] Incident [#SRY04139] Carrying original destination when forwarding

Thu Jun 20 04:44:58 EDT 2019

Hi, 
 
I managed to get it semi working (After successfully upgrading my servers from prehistoric versions). 
 
Our client PBX uses the RURI by default, and I changed it to use the "To:" section of the invite 
 
What I have noticed now is that the 1st failover works as expected, but the 2nd failover ends up with the RURI of the 1st failover in its "To:"

As you can see in the 2nd Failover, the "To:" is the RURI of the 1st failover. 
 
Is there a way that I can carry it over? Maybe change the RURI at the first failover? Do I need to change something in the template files? I have enabled the "e164_to_ruri" but it doesnt make a difference to the invite.

as explained try setting the preference outbound_to_user to<br />
"Original (Forwarding) called user" or "Received To header" - on the<br />
call receiving side (user/domain).<br />
<br />
This should help.<br />
