I was curious about this and started looking through the code to
remember how this all worked. I don't see anything specifically that
would truncate setting a channel variable internally, but perhaps it's
a limitation due to how AGI is processed or buffers used for
parsing/interpreting there. There are a number of fixed sized buffers
used in the AGI parsing code. I'm curious, what version of Asterisk
are you using?
I'm not aware of any workarounds other than those you mentioned. If
you wanted to get really into it, you could poke around in
res/res_agi.c and see if you can figure out which buffer is limiting.
YMMV there though.
