Subject: [PATCH 06/11] From Peter Lemenkov via
|
|
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8326
|
|
|
|
Dissector for the Sippy RTPproxy controlling protocol. RTPproxy is a well-known
|
|
(among SIP-engineers) application and it operates using its own simple
|
|
text-based protocol. There are several competing products but all of them
|
|
implements it (sometimes slightly extending).

svn path=/trunk/; revision=51417
|
|
|
|
Add a cast to try and fix
|
|
packet-rtpproxy.c:226: warning: implicit conversion shortens 64-bit value into
|
|
a 32-bit value
|
|
|
|
I'm not quite sure what's going on here, all the values in use are either gint
|
|
or guint so they should all be the same size?
|
|
|
|
svn path=/trunk/; revision=51419
|
|
|
|
Take another stab at
|
|
packet-rtpproxy.c:226: warning: implicit conversion shortens 64-bit value into a
|
|
32-bit value
|
|
|
|
svn path=/trunk/; revision=51420
|
|
|
|
One more 64/32-conversion fix for rtpproxy
