Thanks to all who reply.

i was reading on mitel packetizing audio. somewhere it got me thinking.

On the old axxess with ver xx, ip phone call to ip phone call. All the audio went through the iprc card.

While with the 5000 standard and hcx controler, ver 4.x and up. Ip phone call to ip phone call, on site or off site, once the connection is established, doesn't go throu the cabinet, like the axxess did?

Audio finds its own path, as long as the connection is maintained?

Thanks

Mike

Starting with either 8.1 or 8.2 on the Axxess, they had peer to peer audio you could choose that wouldn't actually go through the IPRC card, although it would still do the call control. The crazy thing was that if 2 endpoints were set to use peer to peer audio and were talking with each other the circuit busy light on the IPRC would not even light.

I'm not positive on this but I would believe the call control would always be controlled by the switch itself. The audio packets would be the only thing that would act peer to peer.

A good test would be to establish a call between 2 IP endpoints and then pull the ethernet cable from the LAN port and see what happens to the call. Obviously this could only be done so as not to interrupt others on the system. (i.e. - after hours, etc.)
