We do not deal with most cordless phones.
Generally, cordless phones were not built to be repaired.
Most are cheap and difficult to repair so even if they could be
repaired it would cost much more then a similar new replacement.
There are hundreds of cordless phone manufacturers and each
one seems to put out a new design every 6 months. There is no way any
single company could hope to gain access to all the different parts and
resources needed.
