[SR-Users] Kazoo like load balancing

[Jurijs Ivolga]

Hi,


Strange part that my LB receives invite with Route header:

U 2015/07/22 10:46:19.531380 10.101.241.55:5060 -> 10.101.237.133:5060

But instead of sending this Invite to: received=sip:10.50.210.9:50365 it
sends back to Kamailio Proxy(10.101.241.55), even if I have following line
in my config.

modparam("path", "use_received", 1)

Maybe somebody have any idea why?

Thank you in advance!

With kind regards,

Jurijs
