[sr-dev] Asterisk realtime with kamailio Load balancing issue for sip user

[Muhammad Shahzad]

Why are you forwarding instead of relaying the message to selected
destination? Forward is stateless and therefore likely to have NAT issues,
specially if destination server is behind NAT or client is behind NAT and
destination server is unable to handle NAT etc. etc.

Also typically dispatcher is used to load balance calls between two or more
upstream server, not for load balancing extensions within one server,
though with some tweaking that might also be achieved but better to do this
kind of thing on destination server rather then on kamailio.

Thank you.
