DTMF does not work for incoming calls, since I have no need for a menu system on my home phone I never noticed until someone brought it up here.

1 - make sure the phone on ooma makes LONG dtmf (older phones tend to do this like the classic 2500 desk phone) - test to make sure it produces DTMF for as long as you hold the key down (3-4 seconds is enough)
2 - call a nearby landline from your ooma phone and answer yourself calling then listen.
3 - now press any key on the ooma phone (the one you tested to make sure it generates long tones) - do you hear long tones on the landline or short "chirps" of dtmf but not long digits (you can verify the long tone is being sent from ooma by listening to the earpiece of the ooma phone and you should hear the tone still going)
I get chirps on the called line which is a problem when I need to activate DTMF operated devices (gates, alarms, etc) that are connected to a POTS line. I've had to resort to calling these devices from my cell which is set for long tones.
I'm just curious if everyone is being clipped down to the first chirp of the dtmf or is passing long dtmf tones.

Wayne - thanks for your help - it may be the volume of DTMF my older phone is putting out is higher than ooma's maximum signal.WayneDsr wrote:Same here. I can play long or short notes and hear all quite loud.
Has anyone forund a workaround or a solution to the problem?
Will speak with Tech Support tomorrow. Or else, will have to dump ooma.

Yes, I guess its a known issue. Tech Support confirmed that today. Unfortunately, I had already ported 2 lines and have to transfer them back to some other provider.
DTMF is such a fundamental telephony standard that it is a shame that OOMA does not support it.

Friends don't remember what Landline Integration was or why we did it.
