[SR-Users] Kamailio High Availability questions

[Andriano]

Hello

have some questions about Kamailio HA + loadbalancers (dispatcher modules)

1. is posible to make HA for RTP media? maybe RTPEngine +redis? is not 
possible to do this with RTProxy? where is some examples?

2. What do Kamailio db cluster module? it can replicate every DB query 
record like normal DB cluster? or better is to use native MySQL cluster 
mode?

3. How is working dispatcher modules in HA? how call is handled and 
htable in memory between loadbalancers endpoint nodes etc... IS it 
posible to do only with DMQ ?

Just need understand how to do basic Kamailio setup with HA and load 
balancers in general, for example if will be 2 phisical servers, in 
every server is virtualisation and every server has 2 VPS. 1 VPS for 
frontend Kamailio loadbanancer, 1 VPS backend Kamailio app with 
accounts, routing logic, LCR, RTP media app etc... between load 
balancers i know maybe is possible to do floating ip, dns round 
robinetc... and if one VPs server down, call will be dropet in every 
situation? or call will not be droped and how to prevent it.

Just need to know in general schema and architecture how to do this real 
HA in Kamailio and avoind sinlge point of failure and where to read and 
learn it ho to make HA in real. In the internet no many docs about it, 
many conference video how good it is, but no good examples with config, 
i did not founded, so will be very glad for any help in these newbie 
questions ;) with single kamailio is many answers, but is realy 
difficult to understand how to do voip HA with Kamailio without single 
point of failure.

Thanks for any answers...
