If your Plantronics CS540A is not providing a beep to let you know there is an incoming call, there are a few things you can try to troubleshoot the issue:

1. Check the settings: Make sure that the ringer volume is turned on and set to an appropriate level. You can adjust the ringer volume using the button on the base of the Plantronics CS540A or through the settings on your phone or computer.

6. Check the settings of your phone or computer, there could be an option to turn off the ringtones of the headset.

The S10 amplifier/headset system sets up like the Plantronics S12 system of which the user guide is included in the link below. As you will notice, it is designed to work with a telephone. It will not work as a stand-alone unit. To connect it to a dsl box, magic jack or any other line you will need a phone.

The CS series of Plantronics headsets can only be used with telephones, using telephone cords. I do not believe it is possible to use this item on any video game system or non-landline telephone.

There is only 1 headset that's compatible with the SP-05 base. It's the SP-06 (part # 24344-01). Take a look at the following link for a picture.

These can be the only things that are causing your problems:

Ringer mute

Press OFF/CLEAR or MUTE to temporarily silence the ringer. The next call will ring normally.

You can change the handset ringer volume to a comfortable level. The ringer can also be turned off so the telephone does not ring when there are incoming calls.

Make sure the ringer is on (page 8).
Make sure the telephone line cord and power adapter are plugged in properly (page 2).
The handset may be too far from the telephone base. Move it closer to the telephone base.
There may be too many extension phones on the telephone line to allow all of them to ring simultaneously. Try unplugging some of them.
If the other telephones in your home are having the same problem, the problem is in the wiring or local service. Contact the local telephone company (charges may apply).
Other electronic products can cause interference to your cordless telephone. Try installing your telephone as far away as possible from the following electronic devices: wireless routers, radios, radio towers, pager towers, cellular telephones, digital telephones, intercoms, room monitors, televisions, VCRs, personal computers, kitchen appliances, and other cordless telephones.
Test a working telephone at the telephone wall jack. If another telephone has the same problem, the problem is in the telephone wall jack. Contact your local telephone company (charges may apply).
The telephone line cord might be malfunctioning. Try installing a new telephone line cord.
Wait for the handset to synchronize with the telephone base. Allow up to one minute for this to take place.

Turn over the S11 base and insert the headset slot. This is at the top of the base. Remove the handset cord from your telephone base and plug into the handset jack (there will be a picture). Using the short cord that came with the S11, plug into the line jack on the back of your base and the other end into the slot on your telephone where you removed the handset cord. Plug the headset cord into the headset jack that is on your S11 base. Connect the the A/C power adapter to the S11 A/C jack and a wall outlet. Put on the headset. Press the handset/headset switch and pick up the handset off your telephone, set it aside to make calls. Slide the configuration switch (on the side of the S11 base) until you hear a clear dial tone.

The correct connection size for headsets used with S10, T10 & T20 is an RJ9. The jack on the back of the T10 and T20 is an RJ9, this is for the cord that runs into the wall jack. The cord itself has an RJ9 on the end that plugs into the T10 & T20 and an RJ11 connection on the other end that plugs into the wall jack. This cord is supplied with the units.
