Hello - I am using Asterisk in my business and have a few remote sites. Currently each site has their own trixbox for phones. All of these sites are on a WAN, so I would like to have each site point to the main site over the WAN for phone calls to save money, however, I don’t want to do this without having some kind of fail over in the event the WAN at the main site goes down for some reason.
Can you help me think of ways to setup either the phones with alt. proxy or some kind Media Gateway to setup this redundancy?
