RTP over a VOIP Trunk

[plshlp123]

Below is a question my Network guy is asking me, does anyone know the answer to this one?


"when an IP phone is in a call session, are all RTP (voice) traffic passing through the BCM, or only signaling traffic during call set up and call tear down?'"

Far as I know, all traffic passes through the BCM, as it doesn't do peer to peer as nicely as the Succession products do. If I am incorrect, please someone correct me.

I don't think this is entirely true, from my experience it looks like the IP sets connect directly to each other. I had to make some routing changes to our VPN server to accomdate this.

But I may be mistaken.

Good point nsantin...
Now that you mention it, I believe that IP phone to IP phone on the same BCM will go direct. However, when going to another site over IP trunks, or out to the PSTN, the traffic will go through the BCM, whereas in the Succession world, IP phones at different sites can go peer to peer once the signalling server has "told them where to go" so to speak.

IP PHONE TO IP PHONE CALLS ONLY USE RESOURCES DURING SETUP AND THEN DROP OUT. ANY OTHER CALL USES THEM FOR DURATION OF CALL
