Thanks Alex I've checked your suggestion but it seems i've to register all user with same contact (AOR)...for example all registered with 1000@domain.But I can't register all users with same contact because I've to allow "intercom" call inside group. Is there any other way?

Hi guys,

is possible to make a group call with kamailio? Example...i dial 1000 and kamailio make a parallel forking to 1001,1002,1003?

In case of yes...every group member (1001,1002,1003) will be resolved by "location"? Because some member is natted so RTPPROXY should be engaged

Yes; the degree to which this is done automatically be can controlled via the following parameters:

If you have these set to support multiple parallel branches, lookup() + t_relay() should just work "automagically".
