Quick Answer: Toll fraud costs UK businesses £38.95bn/year globally. VoIP-specific threats include SIP trunking hijack (unauthorized international calling), credential theft (weak passwords), brute-force attacks on SIP ports, and toll bypass. Resellers can monetise security through: (1) authentication hardening (MFA, IP whitelisting), (2) SBC security features (DDoS protection, rate limiting), (3) call pattern monitoring (anomaly detection),

Quick Answer: Voice quality is measured by MOS (Mean Opinion Score): 4.0+ is excellent, 3.5-4.0 is good, below 3.0 is poor. Quality depends on ITU G.114 latency (<150ms one-way), jitter (<20ms), and packet loss (<1%). Broadband under 20Mb or contended connectivity will fail. Resellers must conduct pre-deployment QoS assessments and recommend upgrades to leased lines

Quick Answer: Ofcom requires all VoIP providers to route 999 and 112 calls to emergency services with accurate caller location data. Fixed users: register address once. Nomadic users: customers must confirm they understand emergency services may not locate them without providing address manually. Resellers must validate this in writing at onboarding.

Quick Answer: The Ofcom and Openreach PSTN switch-off deadline is 31 January 2027. All analogue and ISDN lines will cease. Resellers can monetise this through PSTN audits (£500-£1,500 per site), migration project management (£2,000-£5,000), and ongoing SIP trunk sales (£15-£25/month per trunk). Device-specific migrations (alarms, lifts, EPOS) have highest project value. Start auditing customer sites

Quick Answer: SIP trunks replace ISDN and analogue lines. Wholesale SIP trunk costs £4-£10/month per trunk + £0.004-£0.012/minute calls. Resellers add value through SBC configuration (Session Border Controllers), connectivity bundling (broadband, leased lines), and PBX migration support. Typical SIP trunk resale price is £15-£25/month per trunk + marked-up call minutes. The PSTN switch-off deadline (31

Quick Answer: Hosted VoIP (Asterisk, Avaya Cloud, BT Cloud Voice) costs £5-£12/user/month and requires no infrastructure investment. Teams Phone costs £6.70/user/month (calling extra) and bundles with Microsoft 365. UCaaS suites (Five9, Avaya, NICE) cost £15-£35/user/month but include contact centre, recording, and compliance features. Total cost of ownership differs sharply by use case. Calculate TCO over

Quick Answer: Microsoft offers three calling options. Operator Connect suits SMEs seeking simplicity and Microsoft SLAs. Direct Routing suits enterprises with existing PBX investments and network control needs. Calling Plans are for businesses needing only cloud voice without on-premise infrastructure. Resellers should bundle all three across different customer segments to maximise wallet share. The Three

Quick Answer: UK VoIP resellers must comply with Ofcom regulations covering emergency calling, caller location, and network resilience. The fastest path involves partnering with an Ofcom-approved wholesale provider, registering your business details, and implementing 999/112 procedures within 4-6 weeks. No separate licence needed if you resell rather than operate the network. Compliance and Regulatory Framework
