About multiple phone numbers
Your BlackBerry® device might support more than one phone number, or your device might be associated with a phone number provided
by your wireless service provider and an enterprise voice phone number provided by your organization.
If you have more than one phone number associated with your device, you can switch the phone number that you use as your active phone
number. You make calls from and receive calls to your active phone number. During a call, you can use your active phone number only.
For example, you cannot place one call on hold and make a second call using another phone number.
