Telebit makes a modem called the Cellblazer, specifically designed for 
cellular. I believe it operates at a peak rate of 10000 bps (no, not 9600, 10K).
Unfortunately, it's high-speed protocol is not compatible with any other
Telebit product (yet), so you'll have to use 2 Cellblazers. Telebit claims
that they will be offering a firmware upgrade to their rack-mount modems to
support the Cellblazer protocol. They are also planning a new product (T2500LL?)
that, in addition to the T2500 features, will support leased-line connections
and the Cellblazer. Unfortunately, they don't seem to have plans for firmware
upgrade to the Trailblazers (even T2500!!).

There are a number of telephones specifically made with RS232 connections. 
I know that Motorola produces such a phone (but I don't have the model 
number - it's not here yet).
