4 Press save store your selection.

Make sure you have filters on the lines between your DSL and your phones. Use the line out from the back of your modem to split to your phones if you don't have any filters. You may have to take line 2 from the back of the DSL modem to send to all of the phones. This is usually a filtered source and should isolate your phones from the DSL. Put the filter on any other devices that are sharing line 2 too, fax, computer, credit card machine etc.

Do you have DSL on this line? Make sure you have filters on the lines going to the phones or take the line coming out of your DSL modem and split it to the phones.

Also, try unplugging your fax, computer modem or credit card machine and test the intercom. Sharing one line for several devices can make the intercom unhappy.

Sounds like you'll need to setup the intercom number again.

There is no included voicemail with that phone. You could order voicemail through the phone company, and I beleive it will turn on the "Voice Mail" light.

No. The voicemail is through the phone company

There is a way to delete all calls in the Caller ID log. With the phone system in standby mode, press Menu/Select (key to the upper right of the arrow keys). Scroll (up/down arrows) to Caller ID log. Press Menu/Select again. Scroll to Del all calls and press Menu/Select. You should see a Delete all calls? Press Menu/Select to confirm. There is no corresponding way to delete all old speed dial or directory listings. The manual for the CL82401 is available here: https://att.vtp-media.com/media/p/document2/products/%7B60627918-4BDE-494D-8537-E265D7649708%7D/CL82201_CIB_2_611.pdf . See page 42 for the information on deleting the caller ID log. See pages 36 and 38 for the directory and speed dial items. I hope this helps. Cindy Wells
