When a packet contains a MediaServerControl payload, it is not presented
correctly. The decoded output looks as follows (only the relevant xml part):
Message 1)
Message Body
Media Server Control Markup Language - draft 07
<?xml

<MediaServerControl>

Message Body

The expected output is:
Message 1):
<?xml version="1.0" encoding="utf-8" ?>
<MediaServerControl version="1.0">
<response id="813" request="playcollect" code="200" text="OK"
reason="timeout" playduration="14660" playoffset="14660" name="">
</response>
</MediaServerControl>
Message 2)
<?xml version="1.0" encoding="utf-8" ?>
<MediaServerControl version="1.0">
<request>
<playcollect id="813" cleardigits="yes" barge="yes"
firstdigittimer="5000" interdigittimer="2000" extradigittimer="1000"
escapekey="*" returnkey="#">
<prompt locale="fr_BE">
<audio url="file://annc/LastUnansIncCall.wav"/>
<audio url="file://annc/WasReceivedFrom.wav"/>
<variable type="digit" subtype="gen" value="3284467105"/>
<audio url="file://annc/ToReturnThisCall.wav"/>
<variable type="number" subtype="crd" value="1"/>
<audio url="file://annc/Now.wav"/>
</prompt>
<pattern>
<regex name="mgcpdigitmap" value="x"/>
</pattern>
</playcollect>
</request>
</MediaServerControl>
The most important change is that the attributes are inside the tag and
not outside the tag. The "wrong" Message 1, also shows \r\n, which do not
need to be there.
Pcap file attached.
