This is unlikely to be acceptable to the mass market until the SIP/VoIP setup is simpler and preferably automated, it's especially unhelpful when a large supplier like BT insists on having a proprietary DV service as that is not the right way to automate these installations as it's effectively revenue protection.

Good reason to ditch BT. In the world of VoIP, they are effectively non standards compliant.

Its a closed user group, not traversing the open internet, so you have disadvantage of non-interoperability, but the advantage of QoS. Most networking aware people will reject, but I suspect the majority of BT’s retail customers will just go with it. 😂

They’re all doing it, Virgin Media, BT/EE, Vodafone broadband, Sky, and others. At least you can reject at purchase stage. The problem is when you are migrated and then find you can no longer change the router, that is where Advertising Standards and Ofcom need to ensure consumers are aware before purchase.
