I had the same problem with the standard flash and pulse-timings in
Zaptel.  Some phone-systems use a flash with a length of about 150ms,
which is way too short for the standard Zaptel-config, which assumes
your flash is at least 750ms long, and sees the short flashes as a
pulse dialled "1" (which is what gets sent in DTMF to your caller).
The following changes to the Zaptel-sources fixed it for me:


Index: zaptel.h

If possible, you could ofcourse also program your phone to generate
the longer flashes and leave Zaptel at it's defaults.  Good luck!
