[Freeswitch-users] Bad request answer

[Steven Ayre]

Unsure. It's saying there's more data than there is so FS is expecting
more. It's an invalid packet. You just need to complain to the manufacturer
and hope they release a firmware upgrade.

Out of curiosity, what router and firmware is it? Might be worth
documenting it on http://wiki.freeswitch.org/wiki/ALG
