Mitel MiVoice Business/MCD/3300 / DTMF not working from 5340 handsets
« on: December 08, 2011, 05:04:27 AM »
We are having an issue on several 5340IP handsets trying to dial DTMF tones during a call.
When a user dials out to our BTMeetme conferencing service (connected via a C&W ISDN30) and is prompted to enter their user ID the digits are not recognised. The problem is intermittent and seems to be affecting several handsets. The users have resorted to transferring the call to the secretary who enters the digits for them before transferring the call back to the user. Swapping out the handset seems to help, but hasn't totally eliminated the problem.
Has anyone else had any similar issues?
Where are DTMF tones generated, at the handset itself?
Is there any way to boost the amplitude of the DTMF signal?
Any help would be much appreciated
