By dialing special prefix 999, we have the fax call differently and make sure calls are routed only to carrier who can support fax over VoIP. You can configure the device to automatically append 999 to the 11 digit phone number you want to dial for fax. How to automatically append 999 what you would do is add the prefix digits enclosed in < and > characters, to the digit map entries of the ITSP Profile A/B/C/D settings. Click on Service Providers -> ITSP Profile A -> General Replace DigitMap from \ (1xxxxxxxxxx|\[2-9]xxxxxxxxx|011xx.|xx.|(Mipd)|@@.)\ To\ (<999>1xxxxxxxxxx|<999>\[2-9]xxxxxxxxx|<999>011xx.|xx.|(Mipd)|\[^\*#]@@.) ![Update DigitMap on OBi300](https://4161683604-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LUHjv4EwOoqWXb2by8A%2F-LchOmqy1RSJj0We-0oy%2F-LchQ_5uOocIYPwGppoz%2FUpdate%20DigitMap%20on%20OBi300.png?alt=media\&token=56175888-5730-44b8-9686-ff7258c05539) Click on Submit --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
