Yes, really. The only difference was which L2 channels the RTP packets were flowed onto, which was determined by the MGCP/SIP signalling and interaction with the telephony gateway. There is a **very** complicated state machine that deals with this using some bastardized IETF protocols (COPS IIRC).
Ok, see, now I (like, I suspect, Frank Bulk) am confused again: when you say "which L2 channels the RTP packets were flowed onto", that sounds to me a *whole* lot like "which VLAN on the end-user drop carried the RTP packets from the terminal adapter in their cable box to our concentrator"... which is pretty much the point I was originally trying to make, if perhaps in slightly different terms. Am I still misunderstanding you? Cheers, -- jra
