Re: [asterisk-users] Replacing PBX during a call in progress
Keepalived + heartbeatd allows you to maintain a a floating IP between two machines. If those two machines had configs, internal state synced, and the IP is configured to float automatically between the two based on which is actively up, would it be possible to not drop a call should the active host go down.

I doubt there is any chance whatsoever of that working! For a start, you can't have two machines on the same subnet with the same IP address. It just does not work. And there is all manner of internal state that would have to be replicated onto the new server.

Re: [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?

Re: [asterisk-users] Replacing PBX during a call in progress
That's the same VM guest moved to a different VM host (not really what I was looking forward). In this case it's an entirely new host with Asterisk having no state/session information, but my app would repopulate the session info and try to re-establish the call. Given SIP over TCP I suspect the answer is still now (since opening the connection on a new host would result in a new syn handshake, different source port used by Asterisk etc.) From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Andres Sent: Thursday, January 12, 2017 12:04 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Replacing PBX during a call in progress On 1/12/17 11:09 AM, Telium Technical Support wrote: This was asked many years ago but I thought I would check to see if things have changed.

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? 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?
