Business Voice & UCaaS in New York City
Enterprise cloud calling done right: unified communications with chat, video, and presence; SIP trunking for your existing PBX; and native Microsoft Teams calling — with QoS engineered end to end.
What You Get with FiberX Voice & UCaaS
Voice is the most latency-sensitive traffic your network carries, and it’s the first thing clients notice when it degrades. FiberX designs voice as a system: the calling platform, the trunks, and the underlying circuit engineered together, with QoS from the handset to the carrier so calls stay crisp even when the network is busy.
Whether you’re moving to full UCaaS, keeping a PBX you like and re-trunking it over SIP, or making Microsoft Teams your phone system, we price the options across providers and manage the port so numbers move without drama.
