[Asterisk-Users] delayed pickup in ZAP interface and issue with hang up-s (fwd)

[bogi at tsm32.com]

Hi out there, 

I’m looking for support in regards to configuration of ZAP interface on a 
TDM400P card (TDM04D).I’m running Asterisk v 1.0.7 cvs on White Box 3.5 with 
kernael 2.4.21
I’ve got two problems with Asterisk:
1. When there is an incoming phone call on the zap interface, Asterisk holds 
call for about three rings and then forward it to a predefined extension. I 
assuming that it waits for caller id, therefore I’ve tried to switch it off 
by modification of callerid and usecallerid with no positive outcome. 

My zapata.conf is:
[channels]
language=en
immediate=no
busydetect=yes ; to test when a line is hung-up
busycount=6 ; to prevent suprious hangups
context=from-pstn
signalling=fxs_ks
usecallerid=no
callerid= asreceived    ;(no or any other value doesn’t bring any 
improvement to my setup)
echocancel=yes
echotraining=800
callprogress=yes
group=0
channel=>1-4 

2. When there is an incoming phone call on ZAP interface that was terminated 
by the caller, before the call was answered, Asterisk rings the extension up 
to six rings. I know it is trying to recognize if the call was finished - up 
to value setup in “busycount”.
I’m using asterisk in Australia and I’m starting it with a proper country 
settings - modprobe:
Module 0: Installed -- AUTO FXO (AUSTRALIA mode)
Module 1: Installed -- AUTO FXO (AUSTRALIA mode)
Module 2: Installed -- AUTO FXO (AUSTRALIA mode)
Module 3: Installed -- AUTO FXO (AUSTRALIA mode)
Found a Wildcard TDM: Wildcard TDM400P REV I (4 modules)
Registered tone zone 1 (Australia)
Specify address with base=0xNNNNN
Registered Tormenta2 PCI
registered new driver wcusb
Wildcard USB FXS Interface driver registered
Registered tone zone 1 (Australia) 

The combination of the first issue and this one crate a problem. In my 
experience most of people wait for about 3-4 rings before they hang up. If 
asterisk will hold calls for 3 rings, I will not have chance to pickup any 
incoming calls and then I will have still asterisk ringing extensions in 
spite of terminated calls. So there is going to be a situation where the 
outside world will not be able to call me and from the opposite side users 
are going to hurry pickup “phantoms calls”.
I’ve tried to search the Internet for some info and solutions, but 
recommended solutions were related to country settings. 

I will be grateful for any advice and recommendation, which will help me to 
resolve these issues.
