Hi all, Has anyone built a ser.cfg that can conditionally forward SIP calls to different SIP - PSTN gateways based on the outgoing calls area or exchange code. I'm sure it can be done but I'm not that good with syntax of the ser.cfg file. I know how to route to single SIP GW based on the dialed string but how do I make SER use multiple SIP gateways? Can anyone provide an example of this? Thanks, Paul
