Linksys WRT350N
Current Status
Untested.

Disable SIP ALG.
Comments
Firmware release 1.03.7 on September 14, 2007, introduced an internal change that disables SIP ALG within the software. SIP ALG interferes with Hosted Voice Services, so we suggest trying to upgrade to this firmware version or higher. This router has not been tested for Hosted Voice compatibility.
