A phone system that drops calls, cuts out during important conversations, or goes down entirely costs your business more than just money. It costs you customers. It costs you trust. And it is almost always the result of VoIP infrastructure that was set up quickly, set up cheaply, or set up by someone who did not fully understand what your business actually needs.
Telphi designs and deploys VoIP infrastructure for businesses across the US, UK, and Canada. We handle everything from the network assessment and SIP trunking configuration through to hardware installation, security setup, quality assurance testing, and staff training. Our clients get a VoIP system that works reliably from day one, meets every compliance requirement their industry demands, and scales as the business grows without needing to rebuild from scratch every time.
Certified and compliant across: ISO 27001, SOC 2 Type II, HIPAA, PCI DSS Level 1, and FedRAMP.
VoIP is only as good as the infrastructure it runs on. Network configuration, SIP trunking, QoS settings, security, and failover planning all have to be right before a single call is made.

Every VoIP infrastructure project Telphi takes on follows a structured process. Nothing gets rushed and nothing gets skipped.
Before we build anything, we assess your existing network to understand what it can handle and what needs to change. We calculate your exact bandwidth requirements, identify network issues that would affect call quality, review your compliance requirements, and map your full migration path. At the end of this step you receive a full written assessment report, a network architecture diagram, a compliance audit, and a clear migration roadmap with timeline and costs. You see exactly what you are getting before any work begins.
Based on the assessment, we design the full VoIP infrastructure architecture for your business. This covers the network topology, SIP trunking configuration, QoS settings, security framework, redundancy and failover design, and integration specifications for your existing systems. Every design decision gets documented and you review the full technical blueprint before we start building anything.
We build exactly what was designed. Network configuration, SIP trunking setup, QoS implementation, security hardening, hardware installation where needed, system integrations, and monitoring setup. We run parallel operation during the cutover period so your business keeps communicating while the new infrastructure goes live. Every deployment goes through a full testing cycle before your team starts using it.
After go-live, we stay involved. Monthly performance reviews, proactive optimisation recommendations, security updates, capacity planning as your call volumes grow, and strategic technology planning for where your VoIP infrastructure needs to go over the next two to three years. Our network operations centre monitors your infrastructure around the clock and addresses issues proactively before your team notices them.

Real results from businesses that trusted Telphi to build and deploy their VoIP infrastructure
"Telphi handled our migration flawlessly. Zero downtime and the call quality issues we had been living with for a year were gone from the first day on the new infrastructure."
"HIPAA compliance was non-negotiable for us. Telphi was the first infrastructure partner that approached it as a design requirement rather than something to sort out afterwards. The result shows."
"Global deployment across 15 countries completed ahead of schedule. The planning and coordination Telphi put into this project was exceptional."
