NBX in SIP mode using an FXS(3CRVG71112-07.

I am having some issues with dialing "0" after being connected to an IVR system.  It looks like the information and digits are being passed but about 20 seconds of music on hold it just disconnects the caller.  What parameter needs to be adjusted to fix the issue?

 

The NBX is version 6.5.22 and the FXS is version 5.20a.047.003.

Re: NBX in SIP mode using an FXS(3CRVG71112-07.

check on your NBX Netset and see what the RTP DTMF Payload type is. This would be in the

System Wide Settings/enable Features System Wide. The default is 97.

Make sure this matches on your FXS gateway... On the gateway, it would be RFC 2833 Payload type should also be 97.
