Inbound routes are very important if you want to have numbers routed to specific destination(s). With this current setup, if you are calling 6784601475 (DID Number) and you are calling from 7702180222 (CallerID Number) the call will come in as it is setup below with music on hold, signal ringing, and a 3 second pause before it goes to the destination set below (Marcus Cell). If your provider does not provide inbound Caller ID, the Caller ID (CID) Superfecta may be a work around.
This module determines how incoming calls are routed inside your pbx. Rules may be given priority levels so that incoming calls will be routed based on how they are seen coming in to the pbx. Be sure to turn off "Anonymous SIP Calling" so that you will be able to receive calls . By setting up Inbound Routes you can have setup a few rules to route to specific destinations, the fewer the amount of routes the faster the processor can run an process the calls being made If rules are not set correctly then calls will not hit the pbx correctly, and cause calls to fail.
