External Extension on Linksys SPA942

[sinboo50]

I have an external extension working fine using the current VOIP Softphone. I am having trouble getting the extension to register on the Linksys SPA942. I have viewd the 3CX videos on the topic but I must be missing something.

SIP Settings
Stun Server = stun.3cx.com
enable stun = yes

My line configuration is attached:

Also is it necessary to run the proxy client at the same time? I do have that running.

Thanks in advance.. I know this is elementary but I am a newbie.

Cheers,

Bruce

Hi
I aslo have been having the same problem using a Linksys SPA-921 & 942, soft client works fine, but registration fails on hardware, therefore I would also like to hear from anbody who has this type of setup working.

Hi Bruce
After many hours I have cracked it,
EXT no.

SIP Settings
SIP Transport: TCP
SIP Port: 5060
SIP Proxy-Require: Local IP address of 3CX server

Dial Plan do not alter

This config registered immediately for me and allowed me to call extensions within our office.

Still working on it here....

Are you using the current softphone client or just the tunnel client?

Hi
I am using the "Direct" connection as opposed the "Tunnel" in the 3cx voip client.

Hi Pruce
change stun server to another stun server like stun01.sipphone.com
change preferred codec to g729 in all your devices
