Answeronpolarityswitch and no ring back tone

Please do not remove the following line from you file:

$FG_TABLE_COL[]=array (“Duration”, “duration”, “6%”, “center”, “SORT”, “30”, “”, “”, “”, “”, “”, “$minute_function”);

Having both Duration and Billsec fields it is the best option.

After you have both fields on screen please check a call without answer and a call with an answer after 2-3 rings. What do you have there?

Hi frnd,

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.

Thanks again.

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

sip.conf:
prematuremedia=no

Not sufficient. The network operator actually has to provide this service, otherwise the call will stall.
