Inbound Routing Configuration
Inbound routing processes all incoming calls from SIP or DAHDI trunks assigned to the routing. It covers global number flags and call routing through configured rules.
1. Creating a SIP trunk
2. Creating inbound routing
Create inbound routing and assign a SIP trunk. Open the routing by clicking +. Go to the SIP channels tab.
Click New record and then Assign SIP channel. Select an available SIP channel.
3. Creating and assigning a dial plan
Create a new dial plan in the Lines menu. Name it (typically with the company name for shared systems).
Assign the dial plan to the inbound routing via the Properties tab → Dial plan.
Create a new record and select from the list.
This ensures that incoming calls from the assigned SIP trunk will be routed to the assigned dial plan.
4. Inbound routing rules
Go to the Phone numbers tab and create a rule with a specific phone number.
Build a “program” from available applications. Calls are processed step by step according to the configured applications.
In our sample example, an incoming call from the SIP trunk to number 211221270 is processed as follows: first, a ringing tone is played for 2 seconds, then a welcome announcement is played, then the configured lines are called; if they are busy, the call is terminated.
