to encapsulate binary code to SIP body </FONT></DIV>
<DIV><FONT size=2 face=Verdana></FONT> </DIV>
<DIV><FONT size=2 face=Verdana>Does it have to be sent as binary? How about
using something like base64 to encode it first?
<DIV><BR></DIV>
<DIV>You also want to be careful sending a large amount of data in this way. If
your packet gets larger than the PMTU then you'll get packet fragmentation which
SIP/UDP doesn't handle well.<BR>
