16 segments, actually, for 4080 (4096 - 16) bytes.

I've just updated the iax2 vars implementation (bug 7619) to automatically
segment variables into multiple IEs as necessary to encode the full value.
Since the OP was using this implementation originally to do what he wanted,
this should obviate the need to go any further along this path.

My objections to sending variables inside IAX2 packets has lessened a bit in
the past several months (although I still think many proposed uses are
cockamamie), so this could probably be committed to trunk in the next several
weeks.
