I try to make VOIP phone call using
a H323 gateway behind an ADSL router
I get a dial tone from my gateway,
and when I dial I do not hear
anything : no ringing or answer from
the called party.
Do you know what I should do ?21st August 2003 at 15:45 #25043BenGuest
Depends on whether your ADSL router/firewall has dynamic h323 support. If not:-
Find out what UDP ports the gateway is using for voice and configure these for static PAT on the ADSL router. Also configure the standard H323 signalling ports as static PAT on the router. I think it will also help if your h323 gw allows you enetr a NAT ip address in the config. That way ti will use the right IP when it embeds its IP in teh H245 messages…#
Hope this helps…21st August 2003 at 21:14 #25044vurcosGuest
I have a linksys router that does NAT. In order for me to make VoIP calls from Internal Gateway I setup Port forwarding.
application: Port #:
2 way audio isn’t an issue when setup properly. Please be aware not only is the setup for SIP similar, but you also have to take into account the Port numbers vary by Manufacture.
I hope this helps.
Most gateways & phones have a config option for such applications.30th October 2003 at 00:16 #25045FredGuest
Which linksys router are you using?31st October 2003 at 23:05 #25046Dan CGuest
Fred … it sounds like you are not getting out past the router to the outside world. Did you set up the port forwarding?1st November 2003 at 00:17 #25047FredGuest
Yes. I set up port forwarding and it works for SIP : I can make a SIP call but I cannot make a call using H3232nd November 2003 at 19:27 #25048froggerGuest
try putting the ip of the device in the DMZ.
