[cisco-voip] Home cable telephony or VoIP vs our IP telephony

[Lelio Fulgenzi]

Hi Sandy, 

This problem plagues us from time to time and then goes away. I got some "insider" information once which which made sense, although I can't confirm it. The person essentially said there is a bug out there that has to deal with in/out-of band DTMF and the central office switches need to be patched and many of them are not. When users have a VOIP solution and/or sometimes use a third party LD provider, they may be routed across a switch without this patch. 

If you have a gateway that you can turn on debugging on, the best you can do is prove to your client/service owner that you are simply not seeing the DTMF. Or, in the case where it is a problem with your setup, that you _are_ seeing the DTMF and it is not being handled properly.

Hi everyone, 



We’ve been having problems reported that people calling from home, where they have VoIP telephony or cable telephony, and when they dial our number and enter digits to reach an extension, the digits aren’t recognized correctly from our Auto-Attendant (UCCX 7.0(1)). They get another extension and they have to try again. Sometimes it’s ok, but it’s annoying enough for them that they call support to complain. Is it on our side that we need to adjust something? Has anyone had any similar issues yet? 



Thanks and regards. 



Sandy.
