Hi All,

Need help again.

My elastix server is behind NAT. I can access ssh/http/https from any where over internet. I forwarded 5060 and can use a extension from a real IP (same ISP who gave me connection at office router/NAT box). When I try to register an extension from else where (another NATed host, i.e from a public wifi hot-spot) it is not registering. Can anyone suggest what to do?


Regards
Jimi

Hi.

Maybe you haven't set the DNS!?
Put some parameters into sip_nat.conf too.
localnet=192.168.1.0/255.255.255.0
externip=your_public_ip or
exernhost=your_domain

Set nat=yes into every remote extension.

Else, that's all.

hoo ....it's only for the SIP protocol.

About the IAX2:
IAX2 not need the nat config (nat=yes/no) and the rtp port.
IAX2 use only one port. ;)

Thanks Dan, I tried all you said for SIP extensions. It seems that the ISP is blocking SIP (5060 to 5065) ports. Is there any way to call directly from Elastix web-GUI? I mean, in address book there are call buttons (green handset) but is it possible to make a call from this page? Or is there anything else available ????

If your ISP is locking some port 5060 at 5065, you could take another port 5070 for example. If isn't the SIP protocol instead of port. :huh:
Else, you could try to use an IAX2 protocol (with a softphone). The port is 4569.

Yes you could use the button to call from ELastix Web GUI. but you should be registered into Elastix with your extension!

It worked ....... An IAX extension saved my day...... It was very easy and straight forward solution. Thanks dear, I am glad.
