Hi all,
There are a 3 sites that have site-to-site vpn connections (and they are on different subnets).
3cx v.11 server is in site 1.
All was fine with internal calls between sites (we had a lot of other issues with TMG though..) until we had gateway for 3cx configured as site1 vpn server (Microsoft Forefront TMG 2010).
Now 3cx is configured to use another router as a gateway (that is still in site1, just different router, different public ip).
All works fine, except there is no audio for internal calls between site 2 and site 3. Phones ring, just there's no audio.
Router has routes added, it is all fine with external calls from all sites, it is also fine with internal calls between site 1 and site 2, as well as site 1 and site 3.
What am i missing?...
Would adding 2nd NIC to 3cx server and configuring it as described in http://www.3cx.com/blog/docs/network-configurations-supported-3cx-phone-system/ "Multiple internet gateways (used by ISPs that offer VoIP Services)" and configuring routing on the 3cx server fix this problem?
Thank you!
