For the record: you can. But it's not really a good idea. Two options:

1. ssh -D: "dynamic" port forwarding. Which basically means that it
creates a socks4/socks5 proxy. You can now use e.g. sockify and connect
UDP-based programs over that connection.

2. ssh -w: create a tun device and create a tunnel on top of that (root
access of some sort is required).

That said, the ssh connection is TCP. The basic reasoning in
http://sites.inka.de/sites/bigred/devel/tcp-tcp.html applies to the VoIP
UDP payload as well.


Oh, and for the record, you can tunnel practically on top of anything.
Just in case you're not familiar with it: IP over DNS (which means you
don't even need direct access, and can use proxied DNS queries).

I figure you won't get quality audio with that, though.
