Hi looking to install Unifi VIP 5mb. Details and clarification below:

1. Location, Jalan BRP 3 Sg Buloh 40160.
2. Existing Streamyx 1 mb user
3. Can I keep my old house number but billing covered under Unifi?
4. Any cash rebate? Registering through TM website, 1 month rebate given.
5. For LAN cabling, running on top of ceiling discuss with contractor during installation date or ?

Thanks.

Also, got this info from web, for those already have existing phone number:
TM give you 2 Phone Line with FREE RENTAL (SAVE RM25 x 2 = RM50)
-one old existing line
-one new unifi line
But both no charge for rental. Kindly confirm yours. Thanks.
