    Please refer to this picture:

    Start with User Initiates Call - determine whether the type of the phone is Phone or SIP URI. If the type of the phone is Ph is Phone, go to user=phone (number 2 above). If the type of the phone is SIP URI, directly inbound Routing (internal) Routing), from the internal route directly to the corresponding end user (picture number 1 above).

    If it is judged that the type of phone is Phone, it is judged whether it is a normal call or an emergency call. If it is an emergency call, skip the Reverse Number Lookup (the process of reverse lookup, serial number 10) directly to the location policy (via the PSTN in the location policy) Usage , where PSTN usage contains associated routes and voice policies. After applying the corresponding policies, the emergency call is routed out to mediation server (serial number 8), and then to the PSTN gateway, and finally to the external terminal user (serial number 9).

    If it is judged that it is not an emergency call, go through the normal phone call process and determine which Normalization Rule is in Global (No. 5). If it follows the internal Normalization rule, the phone is an internal call. Perform reverse number lookup, match the corresponding number (serial number 6), perform inbound routing, and route to the internal client.

    If the judgment is not emergency call, the matching is not the internal normalization rule, and the external normalization rule does not match, there will be 404: No matching rule (number 4) in the log; if it matches the external normalization rule, then proceed Reverse Number lookup (inverse query, in fact, query the internal Address Book), if the query does not find No match in Address Book, then the Voice Policy (serial number 7), associated with the corresponding routes, routed to the Mediation server, by Mediation The server communicates with the PSTN gateways, and then the gateways goes to the external terminal phone (serial number 8-9).
