asterisk users - Oct 2003 - X100P/ATA186 not playing nicely...

Howdy y'all,

I am using an ATA-186, through Vonage, connected to my X100P.  It works
well - except, hanging up...  The hangup doesn't register, most of the time,
with Asterisk.  Are there any known tweaks out there that I should look
into?  I've noted some have altered dsp.c, and rebuilt.  Just curious to see
what y'all think.

Below is my zapata.conf file::

[channels]
language=en
context=incoming
signalling=fxs_ks
adsi=no
echocancel=yes
echocancelwhenbridged=yes
relaxdtmf=yes
;rxgain=2
;txgain=1.5
immediate=no
busydetect=yes
callprogress=no
callwaiting=yes
callwaitingcallerid=yes
usecallerid=yes
callerid=asreceived
channel => 1

Regards,
Phillip
