If the elastix and 4FXO gateway are in the same LAN, and you hope to realize the function below:
The extension 801 dials any outbound calls, which will go out through the FXO 1;
The extension 802 dials any outbound calls, which will go out through the FXO 2;
The extension 803 dials any outbound calls, which will go out through the FXO 3;
The extension 804 dials any outbound calls, which will go out through the FXO 4;
Any calls from FXO1 will make the extension 801 ring;
Any calls from FXO2 will make the extension 802 ring;
Any calls from FXO3 will make the extension 803 ring;
Any calls from FXO4 will make the extension 804 ring;
Here we connect them through IP to IP.
Firstly, let us set the elastix.
1. we will create one sip trunk.
here 192.168.1.237 is the IP address of gateway.
2. we will create the outbound route.
so when any extension dials 9+any number, the call will go to the trunk TOVG .
Secondly, let us set the 4FXO gateway.
1. we will go to the page Basic->SIP, and set the auto sip port selection as 10, just in order to avoid the call issue later.
2. let us set the routing.
IP CPN801 ROUTE FXO 1
it means when 801 dials any number, which will go out through FXO 1.
FXO X ROUTE IP 192.168.1.248:2468
it means when gateway receives any calls from the FXO, it will go to the elatsix.
3. let us set the FXO.
here we set binding number 801, so when the FXO 1 receives any incoming calls, 801 will ring directly.
The settings of FXO 2, FXO 3, and FXO 4 are as follows:
