<div><font 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&#39;ll get packet fragmentation which 
SIP/UDP doesn&#39;t handle well.<br>
