<DIV><SPAN class=postbody>Hi all, <BR><BR>I have an existing panasonic analog
pbx in use and a asterisk server with digium tdm400p(2 fxs and 2 fxo).
<BR><BR>channel 1 -> fxs -> telephone <BR>channel 2 -> fxs ->
telephone <BR>channel 3 -> fxo -> extension 15 at panasonic pbx
<BR>channel 4 -> fxo -> phone line from telco <BR><BR>We call in to fxo
(channel 4) and enter the ivr which prompt us to enter the extension number.
After that asterisk will dialout from fxo(channel 3) to other extensions at
panasonic pbx(eg ext 16,17,18 etc) <BR><BR>The problem is when the extension 16
at panasonic pbx answers the call, asterisk can only detect the ANSWER after few
seconds(range from 2 to 20 seconds). <BR><BR>If the extension 16 is busy, caller
gets a busy tone (approximately 10 seconds) before asterisk detects the BUSY
status and run the following commands in dialplan. <BR><BR>I have tried <BR>- to
call from telephone at fxs(channel 1) to pstn number using channel 4, it can
detect the status immediately. <BR>- testing the outcome of settings in
zapata.conf(busydetect, busycount, answeronpolarity, hanguponpolarity)
<BR><BR><BR>Another question, is there any asterisk utility which can detect the
tone on a channel so that we can get its pattern? </SPAN></DIV>
