[asterisk-users] Asterisk choking on voice messages announcements

[bruce bruce]

Thanks for the input.

I am going to check this once I get access to system again tonight.

But I thought the timing source dahdi_dummy is only good for features like
MeetMe or conference rooms? or am I wrong and it has an effect on any type
of calls and checking voice messages?

Thanks
