Conversation was no problem for me, so I didn't even look at CPU load. It will 
depend on the codec used, so you may have been using a computationally heavy 
one. Another factor could be enabling echo cancellation. I assume it's 
linphone you see using 80% rather than some other app coincidentally hogging 
CPU.
