Aavaya SBCE - SIP trunks to multiple ITSP

[stojand]

Hi,

I couldn't find any document with the statement that Avaya SBCE can provide multiple SIP trunks to the different ITSPs.
Is it posible to configure Avaya SBCE to handle two or three SIP trunks to different ITSPs whose SIP trunking services go through the dedicated network link - private IP adresses (not over Internet and public IP adresses)? Is it possible to configure one dedicated interface on SBC for each ITSP SIP trunk?

Thanks in advance,

I have configured an SBC-E to accept two separate SIP circuits using a single public interface. I was told by ATAC that the device does not support multiple public interfaces. However, both of these circuits were from the same telco so the media port range was the same for each circuit.

What you want to do is possible with a single public interface, but be mindful of your media port ranges. Also, you'll need to apply URI groups to your server flows so that the calls traverse the correct circuits. Insert a router in between the SBC-E and telcos to ensure the correct telco receives the call once it leaves the SBC-E.

Thanks mlombardi1,
You are right regrading ITSP services on public IP addresses (services via Internet).
But, our local ITSPs offer services via dedicated private network and this configuration demands that client's SBC must communicate with ITSP's SBC via private IP address (which ITSP provides).
So, my main consideration is that I have to provide for our client one LAN interface for connection to IP PBX, one WAN-Internet interface for providing services for remote workers/clients, and on the end I would like to have one (or additional two-three) interface for these dedicated ITSP's private SIP trunking services.
I've read that ASBCE has 6 nic cards - so, is it possible to use/configure one of them for this kind of configuration. This will be like - new "private" LAN interface???
