Dear, I have this scenario:
- PBX Asterisk 1.6.2.10 with private IP 192.168.0.10
- Behind a Cisco ASA firewall that connects to Internet
- SIP trunk to Net2Phone with these parameters (nat=no):
host=200.58.113.60
username=DOLLY
secret=123456
port=5060
type=peer
dtmfmode=rfc2833
disallow=all

Xlite (Configure Net2Phone A/c) --- Cisco ASA Firewall --- Internet cloud,
if the above works then there is no problem with your firewall, replace the
nat=yes and canreinvite=yes
otherwise you have to allow the ports 5060 (TCP), 5000 to 3 (UDP) in
your
