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

[Jason Evans]

Thanks for the response Wes:

1. I'm using the CM Conference Bridge Software - default Device Pool, no
Location configured. 
2. All the routing seems to be fine - I double checked, and nothing is
getting blocked on the firewalls. What bothers me is that another user
in DC - same subnet, phone, firmware load - can do it, but this guy
can't. And now there seems to be a user in Austin with the same problem.
