Route calls betwen clusters

[Rod.Blackie]

Hi

I have a UCM cluster in the UK and One in France. Both systems are unique to each country.

I have a VPN that connects the UK and France.

What is the best way to route (on-net type calls) between each cluster over the VPN.

Thanks

Hi Rod.

H323 ICT is an option but you can also use a SIP trunk between cluster but I usually prefer H323.

Have a look to SRND

Assuming both clusters are 8.6 or higher, we recommend a SIP trunk.

If there's anything below 8.6 in the mix, an ICT.
