I was just curious to what your redundancy solution is. I have considered many options, so I thought I would share and get an idea for what others are doing. My setup is two different locations with a 10MB WLAN fiber link between the two. Each location has it's own PRI as well.
I have considered and tested many options this last year or so. 1) Using hearbeat and drbd to monitor the servers. When the primary fails the backup will assign itself the virtual ip used between the two, and then mount the drbd disk which has the asterisk configs and voicemail. The biggest con to this is hearbeat just monitors a ping response either over IP or a COM port. So if the asterisk service dies, heartbeat will not fail over. Although I think there are work arounds for this. The newest version is suppose to have support for monitoring a TCP port as well.... 2) Have two servers with the same dialplan. One in each location. Each server has it's own TDM cards installed. Phones on Site A will register with the server on Site A, and phones on Site B will register with the server on Site B. Then using Polycom phones, they will failover to using the server not on their site, if their primary isn't available. I have setup scripts to copy the dialplan from one server to the other then reload asterisk nightly. The biggest Con to this is I have to be sure my dialplans don't get different. The user's voicemail wouldn't be available until their primary server is back up, but that's OK. 3) Having a main asterisk server and a smaller VoIP gateway at each site. The gateway is a small 14inch deep rack server with a P4 and 1Gig RAM running asterisk. It will host the TDM cards, and just handle traffic to/from the PRI. The main asterisk server will just see it as a SIP trunk. The failover here is that the polycom phones will register with the gateway if the primary server isn't available. They won't have all the features and voicemail, but at least they can dial out and get 911 if needed. What do you think? Do you have a better solution?
