3CX Gamma Horizon or RingCentral for a UK Small Business Before the 2027 Landline Switch-off
UK small businesses still on analogue lines must move to a cloud phone system before Openreach's 31 January 2027 switch-off, after which business lines get no fallback and old-line rental prices are doubling. 3CX is the cheapest licence per extension for offices with IT support, Gamma Horizon bundles everything through a local accredited partner from around £9.95 a user a month, and RingCentral's £19.99 Standard plan suits offices that want deep CRM and Microsoft 365 integration.
