I'm traveling this week, but I'll take a look of this next week if nobody look into before. Could you please send the capture file? 

Thanks

Voip graph analysis for MGCP seems to be missing several messages since
ethereal 0.10.11. (I also tried yesterday's svn checkout, no difference)
Now it starts with the CRCX (create connection), the NTFY hookdetect/digitsmaps
are missing.

Attached the ascii output from ethereal 0.10.10 (+ Francisco Alcoba's initial
patch to save to an ascii file) and 0.10.11 showing the initial 6 messages
missing.
