Transfer a call to any outside number (including cellular phones)

While talking to the first party:
1) Press “Transfer”
2) Call the # you want to transfer to
either:
a) Wait for the person you are transferring to to answer, and tell them about the calling party, then hang up to connect or press “Transfer” again to hang up on the person you were transferring to, and speak to the original party

or:

b) Hang up, (causing a “blind transfer” where the person you are transferring to has no knowledge about the person being transferred)
