Hi Community,
I work for an MSP and we have just inherited a client which uses 3CX for the phone system at both sites. I am new to 3CX and am asking for some advice on the current setup and also the best way to fix a few things.
The current setup which we have inherited is:
1. The client has two sites. At each site a 3CX is installed and the handsets at each site go back to local 3CX box.
2. When site B needs to call outside of the organisation it relies on site A to be online. From looking at our firewalls the phones on site B talk to the 3CX phone system at site B and then the 3CX system communicates back to Site A via port 5090. The calls then go through site A 3CX system. This is not ideal as if site A goes down site B can't call out.
3. The way site B communicates to site A is via a simple portforward rule on the router at site A (5090) Not safe at all.
What i would like to know is the following:
1. Are we able to keep both 3CX systems in place at site A and B and establish a VPN connection between sites so that the voice traffic goes across a secure VPN connection than rather a open port out on the net?
2. Can we put sip lines in at site B so we aren't relying on site A to always be online? This way only internal calls go between sites and any outside calls go out the local 3CX system?
Thanks heaps everyone and I look forward to your suggestions.
Regards
