here's a checklist... First, RTP port range not port forwarded correctly on the NAT router (check rtp.conf).
Then, on sip.conf: externip not correctly setup (it should be the public IP of the NAT router)? nat setting not enabled for any outbound trunk and the extensions (nat=yes) ? localnet not properly setup (to include subnets of local, un-nat'd extensions) ? canreinvite not disabled for any outbound trunk and for the extensions? rgds On Wed, Dec 18, 2013 at 8:34 PM, alp...@gmail.com <alp...@gmail.com> wrote: > Thank you Eric for your reply.
