If a extension do not have "outbound route" for certain destinations, calls is dropping without any prompt. Users cannot understand if this is a system problem or they can not permitted to this destination.
It would be nice if you can put an option into "System Prompts" for extensions which is not allowed to call. Then we can set an promt like "you are not allowed to call this number"
We got this question for a "Yeastar K2 IP PBX" lead.
