Disable SIP ALG or replace the device.

Comments

Netopia has SIP Passthrough “on” by default and will not work properly with Hosted Voice Services unless SIP ALG is disabled. (Or SIP ALG in newer models.) In order to work with Hosted Voice Services, you must turn SIP Passthrough (SIP ALG) off. Note that not all Netopia routers may allow this change; if yours does not, you must replace the device with a compatible router to use Hosted Voice Services.

The SIP ALG setting is not in the web gui. You have to telnet into the router.

Type:

• configure
• set ip sip-passthrough off
• save
• exit
• Restart

On the Netopia 4622xlt, Telnet into the device. Use the arrow keys to highlight the ‘quick menu’ and press “ctrl-n,” which will bring you to the console.

Type:

• ip nat alg sip enable no
• save
• exit
• restart
