Hi Carsten,
Thanks for reply. No idea how this happen but after increase the shared
memory used to run Kamailio , this 500 issue is gone now.
BTW, REGISTER being routed seems wrong in my config file , therefore
after load balancing , client cannot reach each other by MESSAGE.
Client --- > Kamailio LB --->Sip01
\ ---->Sip02
Any idea??
Best Regards,
chanea
