Known Issues

  1. The Frys FR-300RTR is essentially a $30 rebranded D-Link DIR-615 E1 router.
    • Like the rest of the D-Link DIR-series routers, it has SIP ALG enabled by default, which causes intermittent one-way audio at the start of calls and other inbound call and transfer failures.
  2. DNS proxy is also enabled by default, causing intermittent registration failures on Polycom phones.

Resolution

Follow the instructions for the D-Link DIR-series Routers since the interface is almost exactly the same.
