VoIP and unified communications: replacing the office phone system properly
Almost every VoIP complaint we're called out to investigate turns out to have nothing to do with the phones. It's the network underneath them that was never prepared to carry voice traffic.
Moving off a legacy PBX onto VoIP or a unified communications platform is usually framed as a phone system decision. It isn't. Voice is one of the least forgiving types of traffic on a network — it's sensitive to latency, jitter and packet loss in ways that email and file transfers simply aren't. A network that handles everyday business traffic without complaint can still produce choppy, dropped or delayed calls the moment voice is added to the mix.
Where call quality problems actually come from
In our experience, the majority of "bad VoIP" complaints trace back to one of three causes: no Quality of Service (QoS) configuration prioritising voice packets, an internet connection with no dedicated bandwidth allocation for voice, or Wi-Fi-based handsets on a wireless network that was never designed with voice roaming in mind. Replacing the handsets doesn't fix any of these.
What a proper migration actually involves
A migration that's done properly starts with a network readiness assessment — measuring current latency and jitter, confirming router and switch support for QoS tagging, and sizing bandwidth for concurrent call volume rather than best-effort. Only once that foundation is confirmed do we move to platform selection and number porting.
Unified communications is more than a dial tone
Modern UC platforms bundle calling with presence, chat, video meetings and screen sharing into one client. That consolidation is genuinely useful, but it raises the stakes on network readiness — a platform carrying calls, video and file sharing over the same connection needs more disciplined traffic prioritisation than voice alone ever did.
Porting numbers without downtime
Number porting is usually the part clients worry about most, and it's also the most manageable if it's planned properly — overlapping the old and new systems during a defined cutover window rather than a hard switch, so no inbound call is ever at risk of being dropped mid-migration.
