If both VOIP Gateway in two endpoint support modifying the H.225 Q.931 TCP port ( like change to 1721 ), change them; 2. Most VOIP Gateway can’t modify the TCP port of Q.931, try to use some Port Mapping software like : PortTunnel http://www.steelbytes.com GDataPipe http://www.gwacc.co.za/software.htm PortMapper http://www.analogx.com So it should works like : VOIP—1720—PortMappingComputer—1721—–Internet—–1721—PortMappingComputer—1720—VOIP Good luck. 28th September 2002 at 17:19 #20337 Ahmed HashimGuest Can someone please tell me of a product hardware that is not needed on both sides that can pass through \voip calls currently the ISP has blocked please respond ASAP thank you 10th November 2002 at 18:32 #20338 kevin grayGuest ahmed you can do it with gateways at either end depending on the kit your using. if you want to discuss let me know! 12th November 2002 at 20:49 #20339 AhmedGuest Kevin please explain what you mean 20th December 2002 at 06:43 #20340 Mohammed HusseinGuest The only backbone for internet in kenya is Jambo net but for reasons unknown they have blocked VoIp thus i cannot get connection to net2phone servers please can someone advice me how i can go over it, thanks Mohammed Author Posts Viewing 5 posts - 16 through 20 (of 20 total) ← 1 2 The forum ‘Voice over IP’ is closed to new topics and replies.
