I have a Siemens 2 line cordless phone with answerer that with line RFI
filtering seems to work ok in KW environment.  The Siemens phone works very
poorly at my home though and does not have sufficient range to use even in
the next room.  Very poor range.  It also has several software problems
including the dial back does not work now that you have to dial 10 digits,
although the directions say it will work.  It also will not get the Callers
Name from the Dial Directory if the Caller ID does not include the name
which in the case of an ISDN phone line is none of the caller ID's have the
name listed. Half the time you cannot answer the phone from the remote and
my wife now refuses to even use the Siemens phones anymore.

So looking for another good cordless phone system:  The web sites offer so
little information that I need to find someone who really likes theirs:

Work in KW environment so can be used during contests.
Range sufficient for 10 acres (750 feet) and log house walls.
Pick up name from local directory (like my mobile phone does) for caller ID.
Allow 2 to 4 handsets and answering machine. (I have ISDN digital line - but
that only affects not getting name with caller id)
Intercom and transfer to other handset is convenient for antenna work and
getting calls back to rest of family when you answer one in the shack and it
is for someone else.
Good talk time so it doesn't have to set in the charger most of the time.

Any suggestions appreciated.  Please reply to w5fl@ev1.net as well as the
list as I haven't received a message on this list since before Christmas.
