Hi Experts,
I have a Cisco ASA 5510 running 8.4(5) software version and my asterisk server is placed in the DMZ. The asterisk server is NATed with a public IP and forwarded the SIP port 5060(tcp/udp) and RTP 10000 - 20000 (tcp/udp) to the server. I can register the phone and make calls using public IP (of asterisk server) but can't here anything.
Is there any other ports needs to be opened?
Regards,
Ejaz

Hi,
can you see on the ASA any blocks / Drops?
Perhaps the RTP Port Range is another, than 10000 - 20000. For instance, Cisco uses UDP 16384 - 32767.
