[sr-dev] SIPTrace and IPv6

[Carsten Bock]

Hi,

just for the record:
It turned out, that the messages were actually beeing sent out, my
tcpdump was too restrictive.
The INVITE's are beeing sent out and i actually see them in a trace on
my capturing host.

The problem changes a little:
- the problem seem to occur, when i'm receiving a fragmented IPv6 UDP
Fragment on the capturing host (i see both fragments in my trace)
- as soon as i switch to IPv4 for receiving tracing-data, it works...
(even with fragmented IPv6 SIP-Packages).

Since switching to IPv4 for transmitting/receiving tracing data is no
option for me, i'll dig further...
