We've setup a few Polycom 650's and are having problems with dtmf. Initially dtmf wasn't working with most IVRs we dialed into. I've gotten that working but now that we're testing we've noticed in-call feature codes are not working.
I can pick up the phone and dial *97 and get voicemail so dtmf seems to work ok when not in a call.
Dialing ## and *2 do nothing while in a call, you can hear the tone play back but that's it.
I found some advice online and tried changing the following in spipm_sip.cfg
tone.dtmf.level="-9"
tone.dtmf.channel.masking="0"
tone.dtmf.rfc2833Payload="101"
I've also tried with a soft phone and ## doesn't work so I'm not sure it's an issue with the Polycoms.
Does anybody have any suggestions?
