Tek Savvy to provide cable internet

I have just arranged for Tek Savvy to provide cable internet in a house I'm moving to at the end of June. I thought ( for some reason ) that it made some sense to also have them provide the home phone service. Talking to one of their sales folks, I discovered that I could not maintain my current phone number ( that I have had for about 20 years ) unless I used their Voip service, but this forum is certainly giving me pause to question this - especially the previous post. Can anyone else verify the fact that you cannot move addresses and switch to TekTalk at the same time ?

We currently have Rogers Home Phone, and thought a cheaper alternative would be nice, but after the years of completely care-free service we've had, I'm thinking it might be better to stick with them.

I have looked for a thread regarding Vonage here, but can't seem to find anything current - are they that good that no one has had any issues with them ?
