I have a problem whit my asterisk box and b200p card. When I call the ISDN lines connected to the box, the internal phones (extension) rings ok, but the caller do not recieve a ring tone. If the people answer the call, every thing is OK, the call is ok, the sound is ok, but I can't generate a ring to any incoming call (ring to the caller). I have a couple of box working in other clients ok.
The box is based on elastix 1.6, asterisk 1.4.33 y misdn 1.1.9
