I had exactly the same problem with exactly the same phone ;-)

When I pressed the flash button, Asterisk interpreted the event as a
pulse-dialed "1". I looked into zaptel.h and found the following line:

#define ZT_MAXPULSETIME (150 * 8)        /* 150 ms maximum */

Every pulse shorter than that value is treated as a pulse-dial pulse.
Since all my phones seem to generate 100 ms flash pulses, I reduced the
"150" to "75" and recompiled Zaptel & Asterisk. The problem is solved -
and pulse-dialing still works.
