Subject: [PATCH 06/13] 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

svn path=/trunk/; revision=51421

Fix Coverity CID 1063335: Unused pointer value.

svn path=/trunk/; revision=51430
