Active call count

Hi I would like to know is there any way in asterisk that i can get the active call count per channel.

i.e the number of the calls that are currently being processed through a particular sip channel.

Please help me

1 if the channel exists in sip show channels. 0 if it does not.

I think you are misusing channel.

For non-guest calls, the core channel name contains the sip.conf section name.
