Dear Mr. Zhu...
I putted this zaptel.conf from my trixbox:
# Autogenerated by ./genzaptelconf -- do not hand edit
# Zaptel Configuration File
#
# This file is parsed by the Zaptel Configurator, ztcfg
#
# It must be in the module loading order
# Span 1: OPVXA1200/0 "OpenVox A1200P Board 1"
fxsks=1
fxsks=2
fxoks=3
# channel 4, OPVXA1200, inactive.
# channel 5, OPVXA1200, inactive.
# channel 6, OPVXA1200, inactive.
# channel 7, OPVXA1200, inactive.
# channel 8, OPVXA1200, inactive.
# channel 9, OPVXA1200, inactive.

But still no work...
I´ll continue broking my brain
