W52P No DTMF sound at IVR
We ordered our first W52P for evaluation and were really impressed by its quality. As we were testing it we noticed that when we dial a number we hear the DTMF tones from the keypad. However, when we are prompted by the IVR to enter an extension number and we press any of the keys on the keypad we don't hear any DTMF tones. It is as if we didn't push any of the buttons. Interestingly enough, the digits were passed onto the IVR silently because the IVR responded correctly and connected us to the desired extension or destination.

We have set the DTMF tones to United States and the DTMF Type to RFC2833. This is our general set up with all Yealink phones and they all work perfectly well with Elastix server running FreePBX We changed it on W52P to INBAND and then to SIP INFO but it didn't help. We loaded firmware and then into the base and back to the latest firmware but that didn't help either. We tried to upload the latest handset firmware by first connecting the USB port to a Windows 7 computer but got an error that there were no drivers available.

We used auto-provisioning as well as manually checking through the web interface, comparing to T28 and T22 configurations but had no luck.

I'll appreciate your advice.
