[cisco-voip] DTMF issues with VG224 but not other phones

[Lelio Fulgenzi]

We have a user who is having problems using a calling card. They are able to traverse the tree successfully up until a point, so they enter 1 for English, etc. but they have an issue where they enter their calling card number. 

The problem is reproducible (as far as I know) across multiple VG224 ports and multiple VG224s. The problem is eliminated when using an IP phone. 

I gather that it does not have anything to do with the PSTN gateways per se (since it works with IP phones) but more an issue with VG224 config. 

I'm getting more information from the client, but just wondering if anyone has any suggestions. 

I've done some searching on netpro forums and found the following debug statements to be useful: 

    • debug vpm signal (very simple output) 
    • debug voip vtsp dsp (a bit more detailed - provides the in/out) 
    • debug voip ccapi inout (even more detailed) 

Any suggestions would be great.
