Which provider wins for WV businesses? Our independent 2025 analysis.
For WV call centres, VoIP quality is everything. Leased lines provide guaranteed bandwidth. For smaller centres under 20 agents, quality FTTP is cost-effective.
A Wolverhampton expert will call you back today.
VoIP call quality is the defining factor for WV call centres. Key metrics: latency (target sub-20ms), jitter (under 10ms), packet loss (0%) and bandwidth (minimum 100 kbps per concurrent call).
For small centres under 20 agents, CityFibre FTTP via Zen delivers excellent VoIP performance at £40–80/month. For larger centres, a leased line's 1:1 contention guarantees consistent quality regardless of what else is happening on the network.
We also recommend a business-grade router with QoS configured to prioritise SIP/RTP traffic.
Allow 100 kbps per concurrent call minimum. A 20-agent centre needs 2–5 Mbps dedicated to VoIP. Add general internet use on top.
Contention during peak times causes jitter and packet loss. A leased line eliminates this with dedicated bandwidth.
Yes — our team configures routers with appropriate QoS rules prioritising SIP/RTP traffic as part of the setup.
