[asterisk-users] hangup occurs after 2 rings with B410P

[Y BAESA]

Good morning, 

I have installed two cards B410P OK for outgoing calls 

concern about a incoming call, a hangup occurs after 2 rings 
I think it must come from misdn.conf 

unfortunately I do not know what variable act for normal operation. 

you have an idea 
with my thanks

Yves
