[asterisk-users] Weird audio problem with remote IVRs + DMTF

[James Lamanna]

Hi,
Some users have been reporting a peculiar problem.
The are having an issue when they dial out to some multi-level IVRs
where you make 2 or 3 touchtone choices and then are connected to a
live operator.
When the live operator connects the operator cannot hear them or
sometimes it results in dead air.
With the one-way audio issue, is it possible that something has locked
the channel into some mode where all audio being sent is muted? (As a
result of DTMF?)

I'm really perplexed by this one.

Thanks.
