'Digital Voice' to VOIP

Has anyone ported out their number to a VOIP provider from a digital voice (BT/Sky/Zen)?

Asking as someone has asked me the process.

As the phone is an addon to the broadband service (Fttc/fttp) surely it is just asking the VOIP provider to port in the number. The broadband service is not dependent upon the phone service.

This should not cease the working broadband.

well this https://community.bt.com/t5/Home-phone-including-Digital/Porting-number-out-from-Digital-Voice-service-without-stopping/td-p/2400979

suggests that at least BT treat the broadband & phone as a package and so ceasing the DV part will cancel the whole package.

@mystreet1 I haven't tried, from my Zen connection, but reports on TBB suggest it is entirely possible from them. It should, to my way of thinking, be possible from any VOIP provider.

Just done a bit more digging, and they are with UW, who call it 'Digital Home Phone'.
Will ask the question on TBB.

@mystreet1 As UW like to bundle things up, be aware.

I only say this as they appear to offer the 'best price' on some power deals, but to get them, you have to have other utilities - such as your 'broadband' connection through them, too.

Indeed, we're with UW though not for broadband, and they're regularly trying to get us to add services with assorted offers. So do your research/costings.

@mystreet1

The answer seems to be that, unlike the case with PSTN lines, there is no technical reason why a VoIP number cannot be ported to a different provider.

However, with a combined service the ISP may lock the two services together for the duration of a contract for commercial reasons.
