1)users REGISTERED at openser
2)INVITE goes through openser to asterisk and back again to openser
then from openser to the respective user agent
3)actually there are 2 call-leg situation at asterisk( no: 2 and no:102)
4)both openser and asterisk running behind single WAN connection and both
are
running with private IPs and in the gateway router inbound packets are
forwarded
to openser
is it feasible architecture as i described above because i want to put
total setup behind NAT
suggestions required
Thanks in advance
