I have 2 Asterisk servers set up–one at the main office and one at a branch office. At the moment each office is running as a separate system, though I have set up extension dialing between the two servers. The gateway/router has all the needed ports forwarded to the Asterisk servers.
Here is an image of my current setup:
The problem now is that the receptionist at the main office needs to see who is available/status of all extensions. Right now she can only see extensions of the main office phones but she needs to see the 2nd office as well.
What can I do to get the phones in the 2nd office to actually be part of the main Asterisk server?
Can I just tell them to register to the main server and use something like STUN? I’m afraid I won’t get RTP streams through consistently. Is there any way I can use the Asterisk server at the 2nd office to be a SIP/RTP proxy for the phones at the 2nd office and have them really be extensions of the main office Asterisk box?
I’m just trying to figure out my options.
