Now we’ve got a trunk setup and a rate card and call plan we need a way for our potential customers to actually connect to our system! One way for them to do this is via an access phone number. To test this I’m going to use the IPKall DID we setup here in FreePBX.
This assumes that FreePBX has been setup with some a2billing custom destinations as described here – http://www.freepbx.org/forum/freepbx/installation/inbound-sip-trunk-doesnt-call-extensions. Sysadminman VOIP VPSs are preconfigured for this.
Setting the inbound access number (DID) in FreePBX
This is changing the access DID we created here
In FreePBX click on Inbound Routes on the left hand main menu
Then select “ipkall” (the DID we created here)
Scroll down to the bottom of the page and change the Destination to “Custom Destinations – a2billing” then click Submit
Don’t forget to click on “Apply Configuration Changes”
Now if we dial our IPKall DID we should be asked by a2billing to “Please enter your complete PIN number”
