[cisco-voip] Call Handler Not Recognizing Inputs

[Lelio Fulgenzi]

We ran into this problem and have not completely found the solution. It comes and goes in cycles. We believe it has to do with voip deployments in the PSTN that are not transmitting DTMFs properly. We talked with one of our providers and they even told us of a patch that a few carriers have had to apply that deals with in-band DTMF. 

Depending on your gateways, Cisco can help troubleshoot with debug and see if the DTMFs are making it to your gateway from the carrier. We had 6608s so we had no option. 

In our case, however, we had reproducable results. It usually had to do with the person who had a different LD carrier on their line, or using the 10-10 LD bypass carriers. 

Not sure if that helps, but I wanted to provide our experience.

We use a Call Handler as our front end prompt for anyone who calls our company, but lately we have been having issues with it. Every 1 out of 6 times the Call Handler plays it will not recognize DTMF and just keeps playing the greeting. We are running Unity 7.0(2) and I have even restarted our Unity server to see if that was the problem. Has anyone run into this issue before?
