The path of least resistance would be to migrate the broadband to a new provider on a SoGEA-based service that also offer their own in-house VoIP based service. The advantage here is that it’s a “one stop shop “. The disadvantage is that it’s less flexible, there’s more tie in to stay with that supplier as the voice + broadband are contractually bundled and it’s thus less flexible going forward and you may be limited to only using it on their own kit and only from within the premises. Also possibly not as cheap for calls and/or ‘line rental’ (ongoing voice service monthly charge) than with a dedicated, independent VoIP provider.
The other option is to split it / have just the broadband provision with new provider and go out to market with the voice/VoIP provision. So you’d need to sign up with a new VoIP provider first, check it all works, then port your existing number to them. However this would also initiate the cease of your existing broadband+phone service - so a better way of going about it is to:
1. Setup the new VoIP provider account and fully test / get whatever kit you may want (VoIP DECT base, ATA, etc etc)
2. Initiate the order to migrate the broadband to a new SoGEA-only service provider. No other voice add-on needed from new broadband provider. The broadband will switch seamlessly on the nominated day that the new provider will confirm.
3. Initiate a porting request with your new VoIP provider to move your existing landline number to them. This typically takes around 7 to 10 days.
Timing wise initiate steps 2 and 3 more or less in parallel to optimise timing and minimise in gap in service gap when getting the number to the new VoIP provider (though you will still have a voice service available by dint of 1 above), but with the new 31-day “right-to-port” safety net the number shouldn’t slip away even if the underlying service has been ceased by the broadband migration.
