[OpenSIPS-Users] Need suggestion for opensips HA

[Bogdan-Andrei Iancu]

Hi Mark,

with SRV you move most of the logic on the client side, becoming 
dependent of it - like if it supports SRV, how often a SRV lookup is 
done, etc. Also, using SRV implies your opensips boxes have different 
IPs - this might be a problem because of the RR during a call. If a call 
is established through the opensips1 with IP1, the dialog will contain 
the RR with IP1; after a switch to the opensips2 during the call, the 
second proxy will not by default recognize the IP of the other server.

with LVS you are fully self sustained - you do not have any dependency 
of the used device , but such a setup is more complex (as all the HA is 
on your side, as provider). So, this is more complex from setup and 
managing point of view, but it is doable.

Personally I'm in favour of LVS or similar solution as I do not like to 
have my platform depending of the uac capabilities.

Regards,
Bogdan
