asterisk users - Jun 2006 - Sangoma A200 hangup detection

Hi,
Does some one experience the Sangoma A20X-ec series card that cant detect
the hangup tone?
I got * server 1.2.5 and running on Centos 4.3, I hock up to two PSTN lines
and each time some one call in and my phone delay 1-2 sec (this is Asterisk
delay nothing to do with Sangoma) and it rings on my phone, however, end on
the day I got not less that 10 empty messages. I found out that Sangoma FXO
port's does not hangup the lines after the external caller hangup the trunk
line's. It take about 30sec later.....so bad. I did feedback to Sangoma
about this and never one of the tries successes....can some one help me on
this? Or this is the nature of Sangoma A2XX card?
I did tried with TDM4XX no hangup issues on FXO port.

My zaptel.conf file
fxsks=3-4                   ...I did tried out ls b4 I ask Sangoma
loadzone=sg

Zapata.conf
[channels]
context = from-pstn3
switchtype = national
usecallerid=yes
hidecallerid=no
transfer=yes
echocancel = yes
echocancelwhenbridged = yes
echotrainning = yes
busydetect=yes
busycount=1
callprogress=yes
relaxdtmf=yes
rxgain =-2.5
txgain =-2.5
signalling=fxs_ks
group=1
channel=>3-4

Any advice?

A couple of things:

1. The switchtype setting is only for PRI lines.
2. Try setting callprogress=no, call progress analysis is supposedly only valid 
in the US.
3. Tune your gain settings until you get an optimal signal level -- google the 
list or the Wiki, it's quite thoroughly documented.
