[asterisk-users] Ring/Off-hook in strange state 6 channel X

[research at businesstz.com]

Greetings List

I have connected my asterisk box with x100 2xfxo and xorcom 8xfxo and all
of them give me the error "Ring/Off-hook in strange state 6".

Whenever the caller hangup, the call continue to execute until it hits the
hard coded hangup. I changed chan_dadhi busydetect=no and callprogress=no
but problem still persist. I also tried to use different PABX in vain. GSM
modem (FUSION100) also produces no useful result

Please help
