[SR-Users] Kamailio Behind TCP Load Balancer

[Daniel-Constantin Mierla]

Hello,

is the tcp load balancer changing the source address, like accepting the
connection from the phone and then opening one to kamailio?

Do you need haproxy because of other reasons or only for sip?

A kamailio load balancer (sip aware) is also quite fast.

Cheers,
Daniel
