Then they had to call customer service to remove the temporary number from their account, otherwise the temp number shows up on caller ID when you make a call

Even if you transfer the existing phone number, people you are calling will have your temp number showing up on their caller ids

This is simply not true, as the temp number was not released and the ported number was not made primary

Ooma kept me informed by email and phone message (to the box and temp number)

Initially, you register for a new temporary number and once the transfer is completed, you can then remove the temp number

Sound as good as our T-Mo @Home service and it is only about $6 in telecom fees.
