Sorry if my post caused any confusion. I'm talking about 2 different locations of the server & client.
My Asterisk server is located at my office and is not behind a NAT or firewall. It is directly connected to my Cable modem.
I'm using a Sipura2002 ATA at home. This ATA is connected to the asterisk server which is located at my office. The ATA at my home is behind a NAT. The ATA sucessfully registers and can also make & recieve calls only the voice is blocked.
The external ports 10000-20000 were not opened on my Asterisk box. Only port 5060-5082 were opened. I guess thats the reason I was not able to hear any voice. Will try that this evening and post my results.
Thanks
Well, as the user stated on the original message, the asterisk server is behind a NAT and the client is also behind a NAT….
if you make it work just by opening ports, let me know..I have never been able to get it to work, that's why I don't use sip, just plain iax2 for everything… J

Subject: Re: [Asterisk-Users] SIP Extension behind NAT,Asterisk on a public domainThanks Michael,
I think thats is the problem, I have opened only ports 5060-5082, I need to open 10000-20000 as well. I will try that and post the result when i get back home.

I would recommend that you do a little research on google, voip- info.org, and the list archives.
To connect to an Asterisk box that sits behind NAT, you need to forward ports 5060 and 10000-20000 too the asterisk box, and you need to configure the externip, localnet, and nat variables in sip.conf.
audio problems are almost always due to the RTP stream (ports 10000-20000) not being forwarded properly, either due to the port forwarding setup or the sip.conf settings.

Subject: Re: [Asterisk-Users] SIP Extension behind NAT,Asterisk on a public domainBy default AMP had NAT=yes in sip.conf, I read in some posts to change it to one, i was just trying my luck if that works. I have tried NAT=yes, The Phone gets registered, I can also make & recieve calls but as soon as the call is picked I dont hear anything at both ends. Does this have anything to do with codecs?

If no nat then why do you have nat=1 in sip.conf?
