    Hi all, I installed OutCall on my computer and connected it to my asterisk server but when a call comes in it doesn't recognize the phone number in Outlook if it wasn't saved in the exact same format as the caller ID. I'd like to modify OutCall 2.0 to use regex and find numbers in Outlook even if they don't match formats. The number comes in from the caller ID as 12223334444 but it can be saved as (222) 333-4444 or 1-222-333-444 or 222 333 4444 and so on. I need the OutCall to be modified with regex to only look at the numbers when pulling from Outlook and it should always match up with the incoming number. Also always add a 1 before the number if it doesn't have one yet so it'll always find contacts in Outlook that has been saved already even if it was in a different format. Please don't message me without reading this requirements and know that you can help me. So I can know if you read my requirements and can actually help me in your message write "Asterisk is awesome"
