Multiple Locations - for VOIP



  • Please see the GIF file below containing a some-what logical outline of what we are trying to achieve.

    Basically we have a primary location that has a Asterisk VOIP server and some employees as well as VOIP phones. All this plugs into a switch, but technically into a soon to be dd-wrt router OR pfsense machine.

    We are going to be bringing on some remote locations which will have some employees as well as some VOIP phones. The Asterisk VOIP server is located at the primary location. I believe we will need a router to router VPN for the remote locations VOIP phones to connect to the VOIP server at the primary location.

    One concern, however, is that any normal traffic, such as surfing the web, downloading anything, checking email, etc, should all be done via each locations local internet. For example, the computers on the remote location end SHOULD be able to access anything on the primary location (VPN) but any web browsing or downloading should be routed through the local router and internet rather than crossing through VPN to the primary location's internet.

    Since ALL traffic does not need to be routed through the primary location internet but we do need VPN to connect the VOIP phones at the remote location to the primary location Asterisk VOIP server, what would you recommend?

    What advantages does pfsense have over a linksys router with dd-wrt installed?  It seems, from the outside, that a linksys router is less money, easier to setup and costs less to operate (electricity).  Will we have much more control or better QOS or voice quality using pfsense at each location?

    SUMMARY: Asterisk VOIP server at primary location. Adding on additional remote locations and thinking about router-to-router VPN or possibly another Asterisk server. There are VOIP phones at remote location. Computers at remote location should not use the primary location's internet.

    Can you discuss this a bit more?  How long have you been using it?  How was the setup?  Why did everything work and then stop?



  • have been using asterisk locally for above 2 years.
    i just only set up broadhand access to remote site.
    so sip over vpn is all new for me !!

    cannot say it has worked and stop or run !!
    up to now it runs well  (1week) !!

    so i have pfsense in main site and dd-wrt on the remote site.
    openvpn server with pfsense

    remote site use pap2 adapter and is connect via vpn tunnel to asterisk server.
    just need to create extension on freepbx.

    once tunnel is up and route ok, work is done !
