[asterisk-users] mISDN & Numeris Signaling (2 channels for 1 call)

[Olivier Fauchon]

Hi.

When I call my Digium B410p, connected to France Telecom Dual T0 RNIS , 
I get :

Jan  8 10:53:56 obelix kernel: [  369.769601] Setting B-channel 4 to 
echo cancelable state on PCM slot 9
Jan  8 10:53:56 obelix kernel: [  369.769657] Enabling pass through for 
channel
Jan  8 10:53:56 obelix kernel: [  369.775764] Setting B-channel 0 to 
echo cancelable state on PCM slot 1
Jan  8 10:53:56 obelix kernel: [  369.775764] Enabling pass through for 
channel

Why a simple call starts 2 channels ? Could this be a mISDN driver bug, 
hardware failure or a bad configuration ?

Thx .
