DTMF Issue with Sound structure voip interface

[cjoseph23]

We have about 15 Soundstructure Voip Interface cards in our conference rooms.  The VOIP card is registered back to Cisco UCM as a 3rd party SIP endpoint.  I followed the guide to configure both the UCM side as well as the voip card.

When I place a phone call - I get connected.  But if I try to pass DTMF to a IVR the it appears the digits are not being passed entirely.  Is there any configuration on the polycom that I would need to get DTMF to pass correctly?

Hello YashPal,

could we kindly keep to the facts and try to find out what the issue actually is before we give a reply like this that may be totally unconnected to the original posters query?

As we are following the SIP standard and offer different ways to transmit DTMF (inbound / outbound) we should be able to figure out what is going on.

In the worst case scenario the original poster should contact Polycom support via their Polycom reseller.
