Scroll down to "Set Destination" section, select "Extensions" option from the radio buttons and select the extension you created previously when you were creating a SIP user. Call from AXvoice will be forwarded to this extension. Click on submit in the end to save changes, as shown below: Note: If you have purchased multiple DIDs from AXvoice and you want to route each DID to different local extension, then you have to create a local extension for every DID you purchased from AXvoice (See help for creating user). After creating the extensions you have to map that extension with incoming DID in STEP 3 & 4. In step 3 you have to enter your DID which you purchased from AXvoice in the "DID Number" field. In step 4 you have to select a local extension on which you want to forward the call to. Repeat step 3 and 4 for every DID.
