Do you have two physical phone lines? Is your BT phone plugged into one and the broadband modem in the other, or do you have one line and they are both plugged into the same face plate (extensions of the same line)?
Sorry to be pedantic but it sounds to me that your broadband may be supplied via your BT line and therefore there is significant risk if you port the number.
It is possible to port the number and simultaneously renumber the BT line so that services are unaffected but the order for the port will need to make this very clear.
AAISP have some experience of this (link
), other VOIP providers may also be able to do it now
