[Freeswitch-users] How to encapsulate binary code to SIP body

[Steven Ayre]

Does it have to be sent as binary? How about using something like base64 to
encode it first?

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.
