I did a blind xfer with my snom360, and got these two cdrs with
**TRUNK**:

Eventlist:

1. 101 dahdi (used to be zap) phone picked up and 200 is dialed for the
snom360
2. 200 (snom360) picks up and answers the call
3. 200 (snom360) hits the Transfer button (101 gets MOH), dials 202
4. 200 (snom360) hits the checkmark button to send off the call 
       (101 starts hearing ringing, 200 starts getting congestion).
5. 202 (eyebeam) answers (101 & 202 are connected)
6. 101 or 202 hang up. Conversation finished.

Here are the two CDR's with their recorded event times:

CDR     start   answer  end
1        1        2      3
2        4        5      6

above, I called into the snom360, and hit the "Transfer" button, dialed
201, and got congestion (101 gets moh until I hit the check key), and
hung up the snom (200). 201, the eyebeam, rings, I answer. 101 and 201
are connected. 101 hangs up, and the conversation ended.

THE SAME PROCEDURE ON THE CDRfix6 branch:

""fxs.01"
<101>","101","200","extension","DAHDI/1-1","SIP/snom360-0829e2d0","Dial","SIP/snom360,30,Tt","2008-06-26 12:16:37","2008-06-26 12:16:44","2008-06-26 12:17:01","24","17","ANSWERED","DOCUMENTATION","","1214504197.4","",""
""fxs.01"

<101>","101","202","extension","DAHDI/1-1","SIP/murf-eyebeam-082c2b70","Dial","SIP/murf-eyebeam,30,Tt","2008-06-26 12:17:01","2008-06-26 12:17:14","2008-06-26 12:17:49","48","35","ANSWERED","DOCUMENTATION","","1214504197.4","",""

CDR     start   answer  end
1        1        2      4
2        4        5      6

Well, time 3 does get lost, but I thought it might be nice to 
be able to link 1 & 2 by the coincident times and say, hey, that
looks like a blind transfer! 

One point of dissatisfaction I have with these is the fact that SIP/snom
dialed the second CDR, not DAHDI/1. But, if I change it, you won't know
that DAHDI/1 was the guy that murf-eyebeam was talking to... tough
choices.

So, I take it from your above words, that you'd like the 1,2,3; 4,5,6;
times
on the two CDR's?

Can anyone lab this up for 1.2; I don't have enough phones, and I'm not
eager
to reconfigure the ones I've got for just one test.... !

Won't it be pleasant to slip in the fix and watch these guys get billed
for calls they were thinking would be free!
