There's a good insight here that bears repeating:

Sales guy is paid to talk on the phone.

Programmer is paid to program.

So you can treat talking on the phone as a reward/incentive for good behaviour by sales guy. "I'll be happy to talk with you on the phone if you can first summarise your proposal".

In bad sales orgs, the sales people may also be held to a contact quota that does not take into account their close ratio. He may be just trying to pad his contact numbers.

...or shotgunning, and trying a lot of weak leads at once.

The thing is, in this particular case the programmer appears to be the sole proprietor of the company. The "programmer" doesn't get paid to program. The sole proprietor gets paid when he makes sales.
