Q: Can you receive calls on your cell phone as an extension with an android app?

Also does this equipment includes voicemail?

From Jackie at 5/22/2016 8:00 PM

Q: How do I announce a call transfer? In other words, I want to transfer a call to another number, but I want to announce the caller before sending the call. How do I do that?

A: Hi Jackie,

To clarify, are you meaning to announce the call from caller ID so the other party sees who it is before picking up?
