What steps will reproduce the problem?
1.Start imsdroid and select video codec H.263-1998
2.Start Linphone (http://www.linphone.org/)with H.263-1998 
3.Make visio call beetween linphone client and imsdroid 

What is the expected output?
No video before the click on "Send video" button of imsdroid
What do you see instead?
imsdroid sends several (41,42,43) H263+ video packets before the click

The client will always send 3 "blank" packets when the session get connected. 
These packets are sent to open a pinhole in the NAT.
