Hi All,
I have a little problem with my freepbx setup. My SIP clients are registered alright and can communicate among themselves on the same network. However , there is only one way audio when i call a client on another network (also registered to the same freepbx box) . The freebpx box is on a different network ( with its own public Ip) from both networks.
Network 1 is nated to one IP, whiles network 2 has clients with already public IPs bt in a different subnet from the pbx. i can hear the audio on network 2 but network 1 sip clients cant hear from network 2…
both networks are on the opposite side of the firewall protected pbx… ( All expected ports including RTP 10000-20000 have been opend…)
what could be wrong? Urgent help is needed pleease… Thanx so much
