RE: Long Tone on Outbound Calling
(09-24-2013 06:06 AM)TheShniz Wrote:  Whenever a user dials out, the user hears a very long (and loud) dtmf tone played out (over the handset or speaker) for a good 5+ seconds during initial callout over the ringback on the line (analog), and then goes away (doesn't matter if ringback continues or hits automated attendant). Any idea what might be causing this?

Thanks,

T22P & T28P (v70)
DTMF is set to RFC2833

I'm having the exact same issues, here is my description of the problem.
Yealink T22 & T28 Failures: An intermittent loud DTMF tone of approximately 2-3 seconds in duration is being generated over the ringback tone on outbound calls, the tone does not affect the call other than to be an extreme annoyance to the Yealink caller as the tone ceases as soon as the called party answers, the frequency of this failure is approximately 50% and except for the annoying intermittent tone on outbound calls all other phone functions seem to be unaffected. The T28 phones are version 2.70.0.141 and the T22 is version 7.70.0.150 that was upgraded from 7.70.0.141 and didn't change the issue.

Any Ideas?
