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

[Prakash N]

Hi Muhammad,

We are following below document for Kamailio and Asterisk integration

http://kb.asipto.com/asterisk:realtime:kamailio-3.3.x-asterisk-10.7.0-astdb


We are plan use one Kamailio with Multiple asterisk  (Queue,IVR
and Conference purpose)


Now calls are landing to asterisk with load balancing using  dispatcher for
Queue and IVR (One asterisk first and next Asterisk for second calls )

But if try to calls extension it is landing both Asterisk server instead
landing one asterisk first and next Asterisk for second calls

Please advice

With Regards

N.Prakash
