[SR-Users] Asterisk realtime with kamailio Load balancing issue for sip user

[Prakash N]

Hi,

    I am facing some challenge with dispatcher configuration with two
Asterisk

    I have installed Kamailio and  two Asterisk server  and Phones
are register with Asterisk through Kamailio
    I have followed this link
http://lists.sip-router.org/pipermail/sr-users/2011-April/068175.html

    Now  i have added dispatcher module and dispatcher list also

    I am try to route all calls to Asterisk with load balance

  Can please advice the step by step configuration to route calls  from
Kamailio   to two Asterisk ( one call first Asterisk and Second call to
other asterisk )

With Regards

N.Prakash
