You can designate a phone to be a specific line. These line options are:
To add this designation to your phone, please format it as the following examples:
2134567890|verizon(service provider/carrier)|2(type of message this phone will receive - 2 = voice only)|1(country code)|home*
By adding a pipe onto the end of the current phone format(as shown in the first example), you can then include any of the phone types to the number and it will be added once the csv has processed.
This will display in the users contact info next to the phone number and can be changed at any time.
Note: Only a 10 digit telephone number is required, all other fields are optional.
