Thanks for the suggestion, but Wireshark already does what you've
suggested. There's an option to save the raw payload to a file. This
file only has the speex frames (no udp+rtp headers). speexdec still
complains about it not being a valid speex file presumably because the
file is missing the header.

Apart from manually constructing a header and prefixing it to the
file, any other ideas?
