IVM handle out going call

[ahoman]

I want to set up the IVm to handle out going call (landline). That is :

When any exten dial e.g. 111, the IVM will ask exten to input landline number, then call the landline number. I set up the OGm and after exten input the landline number, it will use "transfer call" function to call the landline via VoIP gateway.

 

From the remote site exten, If I use VPN to connect to the Axon server (with IVM) and every thing is fine. But fail not under VPN mode, after I input the landline number, the IVM "transfer call" start and my softphone hand up. I have already opened port TCP 5000-65535 and UDP 5000-65535 on the remoet exten router's firewall.

 

Any help?

 

Anyone can use the followings to test my problem (English voice), after login, dial 109(OGM will take the call) for out going call
