Well, this doesn't make things simpler for me :-(

DAHDI is channel from which I call Dial, so it is only accessible in h.
Otherwise I'll not ask this question :-)

There are 2 things I can't understand-
1. how can I know channel name? imho, this will be far easier to have 
something to name bridged channel...
But I guess it is very simple , I just don't know how...
2. where should I call this SHARED function? before Dial, after Dial?

Here is my calling code:
exten =>_10XXXX,n,Dial(SIP/${EXTEN:2}@peer,,g)
exten =>_10XXXX,n,Hangup()

...
and this is what I tried in h:

exten => h,1,Set(CDR(userfield)=${CHANNEL(rtpqos,audio,local_count)})

This can looks different, this is just a try :-)
But Channel is DAHDI, not SIP, so I want to use SHARED.

Thank you!
