The problem is on certain versions of the firmware the GXW seemed to echo back the tone of the last digit or two that were dialed as the out. You won't hear it in the audio because the GXW is sending it as out-of-band DTMF signals to the PBX/phones.

We went through the troubleshooting process, ended up finally getting a syslog dump from the GXW showing exactly when the problem happened, and submitted everything to Grandstream. Unlike Yealink though they are pretty horrible at support, and despite 3 firmware releases since we had the initial problem it's never been solved. In the end we ditched the GXW and put in an AudioCodes instead, problem disappeared instantly.

I can't guarantee your situation is the same, but I would strongly recommend trying a better analog gateway first and seeing if that solves your issue.

Thanks for the info!! Yeah I submitted a dump to GS some time ago. They denied anything was happening on their endWe have this issue at another location. Both are using the same GS model. I will see if I can get an AudioCodes to install

Thanks alot!
