NO JOY Yealink W52P - keypad presses don't work in voicemail system

[Michael Purnell]

I have several Yealink W52P phones running fine on FreePBX 12. Was planning to move to Incredible PBX 13 and have it up and running. One of the W52P phones is registered on the second PBX, but when I access the voicemail from the handset I cannot navigate the menus. Once I'm in, the keypresses do nothing. I do not have this problem with FreePBX 12. I've tried comparing the settings for the extensions, to no avail.

Make sure DTMF is set for RFC2833 everywhere. On the Yealink it's probably in Account->Advanced. Also on the Pbx if it have been changed.
