Thank you. Any way i just replace word ‘duration’ on word ‘billsec’ before u reply and its working fine. Now bill duration field display as billsec and its the correct talking time. I really appreciate your kind help and it help me to have good idea about Astersik.
Also now my system is up and running. I’m really happy.
On asterisk 1.6.2 with dahdi cards - my is ATCOM AX4G - answeronpolarityswitch=yes is required for propper billing reports - the call is reported answered if it is answered by party B. If answeronpolarityswitch=no, dahdi set the channel answered after call is placed to dahdi channel.
If you want to have ring back and propper billing reports set:
dahdi_channels.conf:
answeronpolarityswitch=yes
polarityonanswerdelay=300
hanguponpolarityswitch=yes
