[OpenSIPS-Users] call_center module and loose routing

[Bogdan-Andrei Iancu]

Hi,

So you use pre-loaded route in order to send initial INVITEs from 
SIPSERVER to OPENSIPS, right ?

And what you want to achieve is to have all the calls generated by 
OpenSIPS Call Center (to agents, to announcements) to actually go again 
via the SIPSERVER?
