Conference on remote IP Phones

[rafaelgarcia]

Hi,

I have some outside IP phones behind a pix 501, one phone per pix. These users can make a conference call but the problem is that the people on the other side of the phone can't hear them. Also the phone displays CM down, features disabled.

I looked in the TAC Case Collection and there is an bug but it is not related to this situation. I am using codec G.711.

I need help. Thanks

During SRST failover, the phone unregisters with any or all CallManagers which hold the call forward destinations. All call forwarding information is lost if a phone loses the connection to the CallManager it is registered to and registers with SRST.

Incoming calls that reach a busy signal or go unanswered during Cisco CallManager fallback can be configured to forward to one or more E.164 numbers.
