I just compiled linphone for linux ppc on a 2.4.18 benh kernel succesfully,
and was able to connect to a second linphone on another computer, though
there has been no voice transmission. After a small discussion with the
developer of linphone he wondered about the high latency of the sound card.

This was done on a Pismo.
I wonder if the block size is normal for a Pismo or if this could be the
reason for the lack of voice transmission.
