[Asterisk-video] No video loopback with a Nokia N70.

[julien WICQUART]

Hi,

when i try to make a h324m_loopback  with a Nokia N70 :

asterisk-1.4.9
libpri-1.4.0
zaptel-1.4.4
pwlib_v1_10_3

exten => 1483,1,Answer
exten => 1483,n,h324m_loopback()


I've got this debug :

Do you think, it's a configuration problem or a compatibility problem with the
