[Freeswitch-users] Live Upgrade Techniques

[Anthony Minessale]

or you can put a sip proxy in front of 2 boxes where you can control the
flow of traffic.
when you want to upgrade one, take all the traffic off of it by forcing all
calls to the other box, upgrade it then shift the traffic to the new one.
if that goes well, upgrade the other one too.
