VoIP Phone Systems Toronto
Business VoIP phone systems for Toronto and GTA organizations. Group 4 Networks installs, configures, and manages cloud VoIP phone systems for small and mid-sized businesses across the Greater Toronto Area — saving clients up to 50% on monthly communication costs compared to traditional PRI and ISDN lines. What is business VoIP? Voice over Internet Protocol (VoIP) replaces conventional telephone wiring with internet-based calling. Calls are transmitted digitally using your existing broadband connection, giving you HD voice quality, advanced call management features, and the ability to make and receive business calls from any device — desk phone, laptop, or mobile. VoIP services Group 4 Networks provides in Toronto: SIP Trunking — we replace your existing PRI/ISDN lines with cloud-hosted SIP channels, preserving your current PBX hardware while reducing per-channel costs. You pay for exactly the capacity you use with automatic failover to backup trunks if your primary connection fails. Microsoft Teams Direct Routing — we configure Microsoft Teams as your full PSTN phone system using Direct Routing, allowing your staff to make and receive external calls directly from Teams. Existing business numbers are ported into Teams so clients always reach the right people. Number Porting — we manage the complete number porting process including Letter of Authorization submission, carrier coordination, and parallel operation testing to guarantee zero dropped calls during cutover. Most Toronto-area numbers port within 5–10 business days. Auto-Attendant and Call Queues — professional automated reception with intelligent call routing, time-of-day rules, and voicemail-to-email transcription. Unified Communications — HD video conferencing, screen sharing, instant messaging, and presence indicators integrated into your VoIP system.
