Video encoding is a *very* CPU-intensive task (even a Core Duo 2 CPU is
not able to encode in realtime with every encoding algorithm). So you
have to find a balance between:

- Frame size (look how small is the video window in the SIP phone).
- Bitrate vs CPU load (if you don't need a very low bitrate, you may
send the uncompressed stream or as a series of jpeg frames)
- Quality vs bitstream, The lower is your target bitstream, the lower
will be the resulting video quality, that's obvious.

You will have to experiment with available codecs to find a optimal
combination for your case.
