Hi Kurtis, Why not make a separate profile for each provider?

I'm running FS on the inside of our network as a router/proxy between some SIP phones and DID providers. However, each DID provider is behind a *different* NAT (a property of our VPN setups for them). For instance: DID1 is at IP 192.168.1.1 and DID2 is at 10.0.0.1. I have calls working for each of them when I set the following in my external profile: <param name="ext-rtp-ip" value="10.0.0.2"/> <param name="ext-sip-ip" value="10.0.0.2"/> However, I need to dynamically route between *both* of them. I need a mechanism for setting ext-rtp-ip and ext-sip-ip in the dialplan itself! Is there a set way to do this? Thanks!
