Twilio sends the From number in E.164 format, e.g. +12063331111.
We try to match against 3 variants:
Full E.164 │ +12063331111
Strip 1 char │ 12063331111
Strip 2 chars │ 2063331111
This means it will not match phone numbers stored with dashes or spaces in CRM, such as 206-333-1111 or +1 206 333 1111
We generally recommend storing the phone numbers in CRM with the following format: 5615551212.
CRM will automatically format this visually to the following format: (561) 555-1212. This is completely okay, since this is only visual formatting, when you click to edit the Phone field, you'll see it is acutally stored as 5615551212.
Make sure you avoid saving / storing Phone / Mobile numbers with the following format: 206-333-1111, +1 206 333 1111, (206) 333-1111
