MGW to CM registration between countries

[Boulevard99]

Can anyone offer any insight on registering G450 Media Gateways to a Core CM internationally?

What are the concerns with having a branch office location in another country with a G450 registered back to a CM?

Is there any documentation that would support the design for this?

Example: Can a core CM in NY support 3-4 MGW's registered to it say, in Italy, England, Hong Kong? As long as the remote sites have their local carrier services in place (PRI/SIP/Local DID's, etc..)

Multinational locations is fully supported; However, there are Avaya documents that have latency requirements between sites of this design. the last thing you want is your phones and MG going crackers because of that heartbeat traffic. All depends on your WAN.

A good WAN = no issues.

Excellent. Thank you!

I don't suppose anyone has a link to the Avaya documentation regarding this?

I'll get to searching asap. Thank you again!

I'd be more concerned about international loss plans, types of ringback, dialplan and ARS and stuff that makes the phone networks different all over the world.

It's common for a company to have their division in India or anywhere else register home to the US. What those users in other countries expect as 'ringback' when dialing an international US number and hearing ringback from their carrier vs you grabbing the call and pushing out your NY trunks can be different.

The varying public number lengths of those countries, Alaw vs ulaw in your codec sets, making sure your network regions and procr are airtight as far as making sure DSP selection is predictable and Mr Missouri doesn't get to NY Voicemail with a Hong Kong DSP. That's what I'd be worried most about.

@Kyle555:
Those are VERY important factors to consider and make sure are carefully addressed. Thank you!
