Problems with DTMF tones
ChrisThompson:
Here's what's going on from syslog when dialing via "#" direct to the line port. These tones are not always recognized by recipient:

Here's what happens when dialing via Google Voice (SP1) with the "InBand" setting enabled. These tones do appear to be recognized by the recipient:

ChrisThompson:
I applied the suggested settings by OBisupport and it does appear that DTMF tones are better recognized now. I still get the occasional dropped number, especially when dialing quickly, but it works significantly better.
AndyJ:
It looks like something changed in the 1.2.1(2283) firmware. DTMF was actually working fine for me with the default settings before the upgrade, but is now very inconsistent after the upgrade. Sometimes it works, sometimes it doesn't (more often not).

Hi I have the same problem (but have had it sporadically with using SIP / Sipgate / GV before I had the obitalk too)
ie dialing into conference calls, etc
Once I hooked up the obitalk110, I tried to dial into the secondary google voice account configured, to muck around with the voicemail features-in GV's ivr menu, but Google Voice wouldn't recognize my PIN.
I have decent Panasonic cordless phones kx-tga939t
When I press and hold the buttons on the handset, the dtmf tone stays on as long as I press the button.
But when I listen on the other end (via a cellphone or something), it's only a short dtmf tone, no matter how long I hold down the panasonic buttons
So it seems that my cordless phone does really have press-and-hold-dtmf tones
1. Does anyone know of a dect cordless sys that has press and hold
2. Is there gain or other settings to increase the dtmf tones on the receiving end?
Note I've only configed the obitalk thru the web portal and not directly via web admin, I read they can conflict
Also I do not have a landline to test and the phone is hooked up correctly
Thanks
