What is call routing
Call routing is the process used to route telephone calls across a telephony network.
The process is the same whether calls are made between two phones the same locality, or across two different continents.
Three concepts to call routing
- The outcome this routing rule is addressing.
- The condition statement is used to determine how the call will be dealt if the rule turns out to be true or false.
- Action to be performed if true
- What action will be performed if the condition is found to be true.
- Example: bridge to a different SIP trunk.
- Action to be performed if false
- What action will be performed if the condition is found to be false.
- Example: send the originator a 503 service unavailable message.
Call flow through Sangoma SBC
- Call routing profile is bound to a Sangoma SBC Profile
- An incoming call is processed by a Sangoma SBC Profile
- SBC Profile evokes a Call routing profile
- Call routing profile determines an action to take based on incoming call
- Bridge to another SIP Profile, SIP Trunk
- Routing rules are created in order to direct calls received from one interface, and bridge it out to the next interface.
- SIP profiles or SIP trunks are used to bridge calls.
- Routing rules can be as simple as bridging between trunks, or as complicated as choosing from a different carrier due to costs of routing.
