According to draft-duric-rtp-ilbc-01.txt (the document I'd used), it says:
"The codec has a bit rate of 13.867 bits/s using ... 416 bits per block,
which can be packetized in 52 bytes.

However, draft-ietf-avt-ilbc-codec-01 says, as you point out, that it
should be 50.  I've gone ahead and modified Asterisk to expect the 50 byte
frames, but I suppose somewhere we need to be able to handle both types.
