Disable SIP ALG

Comments

This applies to Hardware Revision B only. Other hardware revisions are incompatible with Hosted Voice as they do not have the disable SIP ALG option. This router has known issues with Hosted Voice Services if SIP ALG is not disabled. We recommend disabling the SIP ALG setting on the router, which is available in firmware releases 2.2.4 and higher. This option is available within the firewall settings under the ‘Application Level Gateway (ALG) Configuration’. The SIP option should be unchecked.

**All routers and firewalls need to have the correct ports forwarded and Whitelisting configured for Hosted Voice Services, please click here for more information.
