[Asterisk-Dev] Extracting specific call from 'iax debug' on a busy server?

[Kris Boutilier]

I've got full debug including a suspect IAX call - I am running with
'notrunking=yes'. I was expecting each IAX call to have a seperate pid in
the logs but apparently not. Given the start data:

Sep 10 11:11:06 VERBOSE[131081]: Rx-Frame Retry[No] -- OSeqno: 000 ISeqno:
000 Type: IAX     Subclass: NEW
Sep 10 11:11:06 VERBOSE[131081]:    Timestamp: 00003ms  SCall: 00002  DCall:

Sep 10 11:11:06 VERBOSE[131081]:    LANGUAGE        : en
Sep 10 11:11:06 VERBOSE[131081]:    CALLED CONTEXT  : macro-out-t1nstar
Sep 10 11:11:06 VERBOSE[131081]:    FORMAT          : 2

Sep 10 11:11:06 VERBOSE[131081]:    ADSICPE         : 2
Sep 10 11:11:06 VERBOSE[131081]:    DATE TIME       : 153770362

How the heck can I extract the debug information for just that particular
call? I was anticipating just grepping out the relevant lines using some
sort of key. The data I'm getting is along the lines of:

...

On a related note, can anyone point to an idiots guide to the IAX protocol?
