Unable to connect using Cisco SLM 224P

I am unable to connect with the unit when it is plugged into a Cisco SLM 224P switch.

The cables or switch ports that you are connecting to are set in switch or hub mode instead of endpoint stations. The MDIX setting needs to be changed to MDI since our VoIP products are end stations.

From the Cisco SLM 224P User Guide:

Change to MDI:

MDI / MDIX ­ Displays the Media Dependent Interface (MDI) / Media Dependent Interface with Crossover (MDIX) status on the port. Hubs and switches are deliberately wired the opposite of the way end stations are wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be used, and the pairs are matched up properly. When two hubs or switches are connected to each other, or two end stations are connected to each other, a crossover cable is used to ensure that the correct pairs are connected. The possible field values are:
- MDIX ­ Use for hubs and switches.
- MDI ­ Use for end stations.
