PBX sip gateway register
I have a ip Pbx , and is linked to a Firewall and then to public network. I can make callls using the sip gateway in New York with no pronblem, but problem is receiving calls? Th esignalling is fine th ephone rings but there is no voice ? on either side.
open port 5600 for inbound connections on your firewall, should work fine!

we have done that but no result .
We have also opend up the following ports. as well
access-list bitsat_access_in extended permit udp any host 64.58.99.159 range 10000 20000
access-list bitsat_access_in extended permit udp any host 64.58.99.159 range sip 5069
access-list bitsat_access_in extended permit tcp any host 64.58.99.159 eq 10001
access-list bitsat_access_in extended permit tcp any host 64.58.99.159 range sip 5069

Just a guess - I assume that "BitSat" provides satellite link - have you checked with them that they do not block VoIP traffic? - most do.
If signalling is fine then SIP port is mapped fine (Default 5060 - but can be changed)
If voice is missing the RTP ports are not getting through - range used depends on your SIP devices / gateway configurations.

ISP provider does not block any sip protocols as we can get sip phones directly registered to the Virtual IP pbx , plus they providing this service to other clients.

In fact your incoming SIP port (are you using 5069?) must also be mapped to the IP-PBX. Whilst this is not generally necessary when your IP-PBX registers with the SIP Gateway because 2 way comms will probably be opened automatically it is necessary for receipt of unsolicited external calls.
if sip phones are being registered, then you should compare the ports being used by the sip phone with the ports being used by your PBX.

all the above done as per access list submitted 08/03/11
Well it doesn't match the topolgy diagram for IP addresses so I have no choice but to give up!
