external ip access of the vici for the registration of SIP

[sarxiejr]

I would like to know on how to enable my external ip where my server pointed to register a SIP phone outside of the LAN network.

I had already allowed the ip of the target PC that want to register to our server and also they can access our external ip thru web but when we try to register a soft phone thru external server of the vici nothings work..

What am I missing?

It might be the externip setting in /etc/asterisk/sip.conf
try to set that to your external ip and uncomment it, if it's commented out.

if it won't help then post the output from the asterisk CLI (asterisk -r) when a phone tries to register from outside

Did you allow the SIP and RTP traffic through your firewall/router?

DomeDan: ill check it in our office later if its the cause of my problem

geoff3dmg: Yes already been added to the firewall

You added it to the firewall, but did you forward the TCP/UDP ports in your router?

You added it to the firewall, but did you forward the TCP/UDP ports in your router?

Please note that for registration it is usually NOT necessary to forward any ports, but some routers will require "port triggering" (or sip algorithm) to be active. Inbound calls for IP authentication (as opposed to Registration), however, require forwarding as the carrier will blindly send the call to the IP and the router will otherwise drop the packets.
