Greetings.
I had set up 3 GSM SIM cards on my VS-GW1600 GSM gateway.
I'd registered 3 endpoints to my gateway.
I'd configured the routing such as all incoming calls from the 3 GSM carriers are fowarded to endpoint 10001.
I would like to foward calls to the two others endpoints if endpoint 10001 is busy (if endpoint 10001 already receive a call from gsm-1.1, incoming call from gsm-1.2 shoulb be fowarded to 10002. but 10001 should be the default endpoint for both GSM carriers)
Please follow the steps below:
step 1: create a incoming routing like in1.1, set call from gsm-1.1 to 10001, in the Advanced Routing Rule settings, click "Add a Failover Call Through Provider " button and set it to the other two endpoints. Save this routing.
step 2: the other 2 incoming routing rule, please refer to step 1. Just change the call from to other ports, like gsm-1.2, gsm-1.3.
Wish this will help you. If you still have problem. Please contact me via skype.
