Unless there have been recent upgrades that haven't been updated on to samknows yet, you cannot get Be or any other LLU. Have you tried putting your number into the Be website?
Unless there is a really pressing reason for it I also recommend people not to go for phone/broadband bundles. Most of them are not much cheaper than having them separate, except for introductory offers, and many of them are associated with 12 or 18 month contracts for one or both of phone and broadband. There are one or two that are acceptable though.
On your exchange, which on samknows seems to be limited to ADSL Max, (up to 8Mbps), from BT Wholesale ISPs such as AOL and many better ones, you really do need to concentrate on finding the best broadband supplier for your needs, preferably on a monthly contract.
If you can get Be then fine, that is the best. But if you go for the phone bundle with them, then if and when you migrate the broadband away you also have to move the phone elsewhere within a short period.
