Can anyone explain how I can route all incoming external calls to a specific trunk to a specific ring group? For example: All incoming calls Trunk 1, for the Ring group 600; All incoming calls Trunk 2 to the Ring group 601; All calls entratntes Trunk 3, for the Ring group 602; and so on. However, there is no use DID or CID. Example If the client connects to the trunk 1, the group should ring 600. If he calls for the trunk 2, the group should ring 601. If he calls for the trunk 3, will play the group 602, and so on. There as "hold" the contexts in relation to extensions or groups? For example: Trunk 1 [instala2100_in], direct calls to the group 600 Trunk 2 [instala1500_in], direct calls to the group 601 Trunk 3 [instala9909_in], direct calls to the group 602 and so on. Will I clarified? Sorry for my poor English!
