[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.)

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)?
