Question about AT&T E2662B Twin Corded / Cordless Phone
I brought this phone system home after having it in my office for a year and a half. I set it up according to the specifications. The first night L2 extension in use was on all night. I deregistered everything and took it to various outlets in the house. I finally got it working. It is now in my basement office and was working well and then I noticed the L1 extension in use was on all afternoon. At one point it went off. I have checked all the handsets and other phones in the house and can not get this to reset itsself. I have it by my computer which is wireless. As you know I can not call out nor can I receive any calls. Help Denise

I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck

SOURCE: Second line not working
The phone will show that "line in use" message when it's not connected correctly.
If your two phone lines come in to one jack, make sure you are using a 4-wire line cord connected to the "line 1 and line 2" jack on the phone. You may be using a 2-wire cord so the second line isn't reaching the phone.
If the two lines are on separate jacks you need to connect line 2 to the separate "line 2" jack.
If you know for a fact that both lines are properly connected to the phone and it still doesn't see the second line, then it's time for a new phone.

I have the same setup in a small office I consult for and I found the intercom problem to be caused by the DSL filters. It seems the DSL filters also filter out the frequency that the phones use to communicate with each other. If any of the phones had a DSL filter on them the intercom and hold button would not work properly with the other phones in the system without filters. Once I took the filters off the intercom and Hold function worked fine.

Do you have DSL on the first line? I would say that you have split the line to the phones so that they are not able to recognize the off hook from your office phone because each phone has a DSL filter. So take your phone line from the back of the DSL modem (line 1) and split it to all of the phones. Put the filter in the line, if you need one before the splitter.

I had the same problem happen to me as well and I took the batteries out of all handsets, and unplugged the base for a few minutes. Then plugged in the base, reinstalled the batteries and it registered all handsets lickety-split. Hope this helps you.
