It looks like linphone uses libavcodec from ffmpeg to do the actual 
encoding and decoding of video frames. I don't know about Ubuntu, but 
ffmpeg in Debian testing/unstable doesn't support encoding h261/h263.

ffmpeg in Lenny/Sid (0.cvs20070307-6) only supports decoding h261 and h263:
  D V D  h261
  D VSDT h263
  D VSD  h263i

ffmpeg in Etch (0.cvs20060823-8) supports encoding of h261 and h263p:
  DEV D  h261
  DEVSDT h263
  D VSD  h263i
   EV    h263p

Run "ffmpeg -formats" to check supported codecs.
