Speed dial with Zaptel issue

[bgriff]

I am unable to use Asterisk Phonebook speed dials on my zaptel extensions. The speed dials work fine from sip extensions. I can dial calls out and in on the zap extensions. When you dial a speed dial code on the zap extension, it goes to a fast busy. The CLI on verbosity level 9 only shows the zap extension go off hook and hang up. It is like there is a dial plan programmed on the zap extensions. Is there a dial plan for zap extensions, like the dial plan on most sip phones?

PiaF 1.2
FreePBX 2.5.0rc3.0
Zaptel 1.4.11
Asterisk 1.4.21.1

Thanks for the help.
