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

[Kevin Thorngren]

It sounds like the audio from the phone is not making it to the CCM 
Conference Bridge.  Do you have diverse routes between the remote sites 
and the CCM?

Can you ping the phone with the problem from the CCM?

Once in a problem state try hitting the "?" button twice quickly.  This 
will bring up the stats for the call.  Is the phone transmitting?

You can also web into the IP Address of the phone, ie, http://<ip 
address>.  On the left hand menu select the first audio stream.  You 
can verify the IP Address and port of the destination.  Does this look 
correct?

Do you have any firewalls between the remote phones and the Conference 
Bridge?
