Zaptel Problem for UAE

hi,
I m staying in UAE… We are using TDM 400P 04b( 4 fxo ) card. I don’t know why this Card is not hanging the incomming calls properly… We are using defaultzone= us …as UAE is not there… I m 100 % sure that this is the problem of signalling voltage… I m using fxs_ks signalling…I tried with different signalling also…but of no use…
I tried all the stuffs like " busydetect=yes, busypattern, hangonpolarityswitch, callprogress…" but all seems to be of no use…

so when i use “show channels” from asterisk CLI …I gets Zap/1-1, Zap/2-1, Zap/3-1, Sip/100 channels…As u can see that 2 of the Zap channels didn’t hangup…Its creating a big problems for us…Kindly help me…

One more thing i was thinking to run in crontab after every 1 miniute…
Can i find out that which sip extention is using which zap channel ???
for example from above how can i find out that Sip/100 is using which Zap channel…??? Like i noticed from FOP that when we are just pointing our mouse to zap channel it shows that which sip extention is using it…I want the same thing from command line…

Kindly help me…

Thanks in advance,
