Avaya CLAN , IPSI and RTP forwarding understanding

[skk391]

Hi all,

Can someone help me with some Avaya / telephony understanding please. I'm fine with most of the day to day config and admin stuff but always been slightly confused with the following.

Phones register with CLANS cards or PROCR - got this down...
IPSI connect the different port networks together ... can understand that...

I need some advise on the following. We have 2 sites with ISDN trunks at each site, both have local CM ESS is case of WAN failure. In normal operations a call can be delivered to site A but then answered by staff at Site B. How is the RTP traffic sent to the phone at Site B? I want to know is terms of networking what in the Avaya world tells / sends the traffic to ( in our case ) to our Cisco routers,which is then forwarded to the Router at site B?

What commands on the Avaya would show this please.

I'd like to understand more on how to managed and do some bandwidth calculations on how much network bandwidth we're using and how to calculate a potential move from ISDN to SIP.

In simplistic team it is no different then a PC in office A, sending information to a PC in site B. Site A PC does not know the physical location of the site B PC, all it knows is the name, or IP address. Your network would handles the flow of data. You main CM server do not physical know the route the RTP stream will take, all it knows is the IP address of the end point, or in the case of trunks or digital set, it knows the port network address, you network will handle the flow.
There are ways to configure your system to best use the DSP resources, etc. using Network region, and network Map. But that depends on how your system and network are built.
