Bob,

A 2500 set? Why would you want something so modern and unreliable?  After
all, this relies on DTMF ("touch tone") generators and decoders :-)

No sir, you want a 300 set. Introduced in 1937, this model generates
pulse-only dialling. [The 500 set, introduced in 1949, works too].

After the 1989 earthquake in the Bay Area, the 300 set saved my day. The
local switch (PLACAL02) would not budge on tone dialling, but pulse worked
just fine (using a non-mainstream LD carrier of course).

Yes, we keep a couple of old "2500" telelphones around
the house too...just for this purpose.  I have often
wondered why someone does not make a modern cordless
phone with backup 2500 set capability built into the
handset (which would need an RJ-11 jack as well, of
course)?...in a power failure, one would then simply
transfer the phone line from the electronic base into
the handset, using the phone line power plus its internal
battery to power the conversation and the buttons/lights
respectively...or something like that...that doesn't seem
too burdensome, given the existing capabilities of the
handsets anyway...does it?

Cheers,
