Hi all
We do have a strange problem with loosing rtp in case of carrierroute - failureroute.
If we send traffic directly to the failure gateway, we do have rtp without any problem
Situation:
Ua --> Freeswitch --> kamailio 3.3 --> gw 1 Error 404 --> failureroute -->
media gateway voiceprompt for error 404
==> this does not work
Ua --> Freeswitch --> kamailio 3.3 rewrite to dest for voiceprompt 404 -->media
gateway voiceprompt for error 404
==> this works!!
Any idea?
For me it seems being a problem with branching or so.
Regards,
Oli
