Making outbound calls

When sending calls from a SIP trunk or from your AVOXI Webphone you should dial all numbers in E.164 number formatting.  This is a standardized numbering plan for the worldwide public switched telephone network (PSTN). It was developed so that associations around the world would have a standard format in which to express telephone numbers and is the primary standard that AVOXI uses. The format is the country code plus the number subtracting any preceding zeros. E.164 formatted phone numbers are limited to a maximum of fifteen digits.  

CLI Formatting

CLI (Caller Line Identification) should be displayed in the same format. This is only applicable if you using AVOXI as a SIP trunk provider. ** If your CLI or Calling number is not in the correct format calls will be rejected.

Below a few examples of numbers from different countries and their E.164 format and CLI:

  • International Country Calling code
    • 86, CHINA
  • Local Area code 
    • 10, Beijing (+86 10 45205937)
    • 21, Shanghai (+86 21 45205937)
    • 755, Shenzhen. (+86 755 45205937)

How to advertise your TrueLocal Number
