Cisco IP Phone RTP data replication

Hi!

I am working on capturing voice data from cisco ip phone 7960.

I understand that the Cisco IP hard phone replicates the incoming voice data on to the PC to which the IP Phone is attached through the Cisco IP Phone access port.

My question is that is there a configuration where i can replicate the outgoing voice data as well to the Access Port.

I am running a sniffer on the attached PC and i can see all the incoming UDP packet data on the PC, but I am not able to see any outgoing UDP voice data packets.

Any help will really be appretiated.

Thanx in advance.

Regards

Kamal

Re: Cisco IP Phone RTP data replication

I guess, the access port of the IP Phone can be configured to replicate the incoming and the outgoing traffic . More on this in the following document:

Hope this helps.
