Multisite unified communication deployment with centralised call control

Mujeeb Shaik

Hi all, trust you are doing well, 

I have a project coming up which requires me to deploy unified communications on be6m on a c220 server and use a 4331 voice bundle as a pstn breakout plus srst and connect this 4331 to other two remote sites each having their own 4331s , issue is we have to establish site to site connectivity and enable voice communication using internet as a medium as the customer does not have dedicated wan links. How do we achieve this. Any configuration samples will be greatly helpful. Currently they are accessing internet filtered through fortinet firewalls in all the three sites. Will these firewalls play a role too and will have to be configured. 

 

Please advise.

With Immense gratitude,

Mujeeb Shaik mohammed

Hi @Mujeeb Shaik

 I believe the simplest way is stablish VPN site to site between firewalls and build the 4331 communication on top of that.

 With a decent internet connection and well configured s2s VPN, is possible that the solution works fine.
