How to get a dial tone on AEG Chamfer 215-2?

SOURCE: brand new cordless handset -- no dial tone, no ring!

I doubt it's the battery. As I understand it the base works fine and the problem is only with a cordless phone. Are you using an external charger stand for the cordless handset? These phones need to be registered to the base unit. That is usually done by installing the cordless phone in the base unit but you may need to do that shortly after insalling the battery or you could have a register button or setting.

My battery is a Ni-Cd. I bought it new on eBay (TL26554 battery number). I allowed the new battery to charge for a long time and then tried to see if it would work. But no go....the handset gave me the same error message. Good Luck to you too! Mmmmmm

SOURCE: handset has No link to base

I was having the same problem with the same model phone, and fixed the problem by rebooting the phone – unplugging the AC and phone cord from the base station and plugging both back it, then removing and replacing the handset to regenerate the security code.

SOURCE: Handset ?No Link To Base? error and no dial tone

2/29 Have you registered or re-registered the handset?
"No link" can mean handset is not accepting radio wave of base unit. At Mfgr website pull-down operator's manual and look for registration instructions. Some sequence of buttons will create a radio signal from base (have handset off base) then another sequence of buttons on handset will accept radio signal. If handset has "menu" button, try "menu", then "00" (zero zero) then select an accept or "OK" button. Good luck.
