asterisk users - Nov 2012 - Actual DAHDI channel number

Hi

I want to know actual DAHDI channel number (pseudo), which received the 
call or dialed the call. Where as when Asterisk receives a call on DAHDI 
channel, it shows channel as "DAHDI/i5/112-15"
Is there any way / configuration to change this behavior and get actual 
channel number? Earlier we used to get this.

I am using Asterisk 1.8.11 and Dahdi 2.4

Thanks & Regards,
Amit Patkar

You can use the AMI action DAHDIShowChannels to get the current
channel mapping.

There is an AMI event that you can look for:
Event: DAHDIChannel
Channel: name
Uniqueid: id
DAHDISpan: 5
DAHDIChannel: 23

It is generated whenever a call is assigned to a B channel or a call
moves to a different B channel.

There is also the CHANNEL() dialplan function:
CHANNEL(dahdi_channel)
CHANNEL(dahdi_span)
CHANNEL(dahdi_type)

The DAHDIChannel event and CHANNEL() function are mentioned in the
UPGRADE.txt file.

I put ${CHANNEL(dahdi_span)} to know the span and ${CHANNEL(dahdi_channel)}
for actual channel number in incoming context of PRI.
For outbound I normally use M flag in Dial() to call a macro and check the
above variables in that macro.
