Configure your origination SIP Trunk
In this article, we’ll show you how to set up the following:
You can receive inbound calls to your MessageBird number from our platform in multiple ways:
Forwarding to a specific PSTN number in E.164 format e.g. +31612345678 or 31612345678
Forwarding to a SIP server/node e.g. your Session Border Controller, IP-PBX, SIP Proxy Server, etc.
Requirements
Add MessageBird's IPs to your firewall or PBX to whitelist them
NOTE: It’s free to make a MessageBird account, but you’ll need to add funds to your account to place calls.
Incoming calls from a Virtual Number to Forwarding Rule (IP-PBX)
Follow these steps:
Log into your MessageBird Dashboard, then click the Numbers icon on the toolbar on the left-hand side of your screen.
Here, you’ll be able to see a list of the virtual numbers you have purchased and see the status of those numbers. Find the active number that you want to set up forwarding for.
Next to the Status column, you’ll see a column titled Edit. Click the three dots, then select Create forwarding rule from the options that appear.
On the Forwarding Rules page, click Create rule. A pop-up will appear.
In the Name field, enter a recognizable name for your forwarding rule.
In the Prefix Number with ‘+’ sign field, select Enabled (default) or Disabled.
In the Domain field, enter the IP or Domain name of the PBX where you want the calls to be forwarded.
Click Save to save your changes.
If you want to assign more numbers to the rule that you just created, click on Add New and select the number from the drop-down.
NOTE: The Forwarding Rule option can only be used to create a flow where the calls are forwarded to a customer-defined PBX.
Incoming calls from your Virtual Number(s) to another Number via your SIP Server
Follow these steps:
Log into your Dashboard, then navigate to Flow Builder.
If you want, you can use our pre-made Forward Flow template. If you’d prefer to manually create a flow, click Create new Flow.
Choose Phone Call as the trigger, and select the number or numbers that you would like to forward calls from, then click Save.
Click the Forward Call step.
In the step settings, add the SIP URL that you would like the calls to forward to into the Forward to number field. Take a look at the screenshot below to see how we’ve formatted this, replacing “1.1.1.1” with your own SIP Server IP.
Click Save.
To see how your flow works before you make it live, click Simulate.
Click Publish in the top right-hand corner of your screen to start your flow!
NOTE: A SIP URI is the SIP addressing schema or identifying string of characters to call another person via SIP. It is, essentially, a user’s sip “phone number”, and it is formatted similarly to email. The format is “sip:user@host, or sometimes “sip:user@host:port.”
