- SIP ALG is enabled by default and cannot be disabled, causing intermittent phone call and feature failures.
- These routers are inexpensive because Belkin builds them with little memory. This causes the router to mismanage the many UDP ports each phone uses, causing calls to cross, intermittent one-way audio, call park failures, and transfer failures.
- Replace the router with a compatible one.
- Intermedia cannot setup the new router for you, but your IT or the manufacturer of your new router can help you. They will need to move settings from the old to the new router to ensure your computers and other devices on the network work properly.
