[cisco-voip] Conference Initiator Unable to be Heard - On-Net calls

[Wes Sisk]

Given WAN, I would check a couple of things:

1. CM builtin conference bridge is g711 only, so you're either invoking
transcoder or using hardware conferencing - which?
2. check all the IP Routes and default gateway from your hardware conference
device or transcoder.

calls


Hi,

Certain users over the WAN are unable to use the Ad-hoc conferencing
feature because when they press the "Confrn" button to join the 3
parties, none of the parties can hear the initiator.

For instance: User A in DC dials user B at extension 1123 in NYC, and
both parties can converse. User A then presses the "confrn" button and
gets User C in NYC at extension 4500 - User A and User C can also
converse normally. However, when User A presses the "confrn" button
again to join the parties, User A can hear Users B and C, Users B and C
can hear and speak normally, BUT Users B and C can NOT hear User A.

Additionally, I tested this scenario with another user in the DC
location and things worked fine. So I have 2 phones on the same WAN
segment, with the same profile and rules - 1 works and 1 does not. The
only discrepancy between these 2 instruments is that the one which is
having the problem is a shared line (with a NYC appearance and a DC
appearance in both places) and one has only a single appearance in DC.

I did a run through bugs and didn't see anything pop out, and most
previous postings on "one-way" voice have to deal with calls going out
of a Gateway. Any ideas or suggestions would be great!

Thanks - Jason
