[asterisk-users] Replacing PBX during a call in progress

Can re-invites be sent AFTER the first Asterisk server has been shut down?  (If the first Asterisk server is still up then it’s a gracefull transition, but I’m assuming the first Asterisk server is simply unplugged).  And can they be sent from a NEW asterisk server?

As Andres mentioned you can use VMWare. Another option would be to send a re-invite to both devices and send them to another server.

This was asked many years ago but I thought I would check to see if things have changed.  Is it possible to take over a call in progress – using a replacement Asterisk server?  

One plausible scenario I can think of is if you are running VMware VMs.  Using the vMotion feature would accomplish subsecond VM live moves.


In other words, if 2 user agents are connected through an Asterisk PBX, and I tracked the call ID, IP of each UA (and anything else needed), could I remove the PBX and put a new one in its place (at the same IP address) and resume the call?  Somehow keeping the call up on the UA’s and telling Asterisk to just resume a call given specified parameters (so the UA’s wouldn’t notice the change)?
