We have 2 offices. Office A has the freeswitch server and some phones. "Office B" is new and we have 2 phones that we want to connect to the Freeswitch server located in office A so that calls can be made by the staff using Freeswitch. The question is how is this done? Here is how I see it but it does not seem to work. Please help! Office A has the Freeswitch server which connects to an external VOIP provider. The Internal clients connect via port 5060 to the Freeswitch internal profile. There phones work no problems. The IP for the Freeswitch server in office A is 192.168.50.50. The Public IP is 142.xx.xxx.xxx. Office B has 2 phones both are configured to connect to the public IP of "office A" on port 5060 which is routed to the freeswitch server. The Phones have a local IP of 192.168.23.6 and 9. The issue is that the phones are never able to register ( both side have identical settings) or transmit a call from one office to the other. Freeswitch does not seem to know how to route the calls to the other office. Ultimately we would like the staff from "office B" to be able to receive and make calls coming into the Freeswitch server. 1) Is this not possible over the Internet? Do we need to set up a VPN between both offices for this to work? Is there a way to tell freeswitch that ext 340 is located in office B? Thanks cjb
