Hi,
is there someone could give me a hint on how to configure this module?
I can see that the call is going out to my external gateway interrogating the
routing table, however I'm getting a CANCEL from Kamailio.
If using this cr_route I can see that users can't place calls themself
(internal calls) because all calls are going out to the external IP.
In my opinion the cr_route should be placed replacing PSTN route, right?
However I'm still getting the problem.
Thanks
Max
