I found this: If the called phone is busy i can ear the busy tone but seems that the visdn channel is ignoring the "busy" indication.
This is the last part of the call...
After the "visdn_q931_disconnect_indication" i wait until timeout.
It is possibile to setup visdn to ignore or not all indications?
Thnks...
