Voice & unified communications
Business phones still matter, and they run on the network. Our team builds and supports phone systems: PBX, SIP trunks, call flows and IVR, plus hosted voice and Microsoft Teams voice.
Our team builds and supports business phone systems: PBX, SIP trunks, call flows and IVR, plus hosted voice and Microsoft Teams voice. We plan the network first, because voice quality depends on it, then port numbers, build the menus and test failover.
Voice is also a place where automation helps. We can add speech-based menus and front-desk agents that answer, route and log calls, with a person always one step away. Offices with several sites get consistent call handling and a single place to administer it.
What we do
- PBX and hosted voice deployments
- SIP trunk setup and failover
- Call flows, hunt groups and auto-attendants
- Custom IVR connected to business systems
- Teams Phone configuration
- QoS and voice VLAN design
- Fax over IP
- Number porting planning
When a menu has to talk to a business system, we write the voice application. Call quality depends on the network underneath, so we design voice together with the network, power and internet circuits.
Voice connects to Managed IT for phones and handsets and to Cyber Automation, where voice menus and AI assistants answer, route and record requests.

How we use Voice & unified communications for clients
Frequently asked questions
Direct answers to the questions we hear most. Something else on your mind?
Send us a messageDo you support Microsoft Teams Phone, RingCentral or Zoom Phone?
Yes. Our team has experience with Teams Phone, Webex Calling, RingCentral and Zoom Phone. Names are trademarks of their owners and appear as experience, not partnership.
Can you move our phone numbers to a new system?
Yes. We plan the port, run the new system alongside the old and cut over at a set time.
How do you make SIP trunks redundant?
Use two trunks from different carriers or at least different points of presence, with the PBX or session border controller trying the second automatically when the first fails or stops answering. Pair that with two internet circuits so a single access failure does not isolate both. The carrier can also forward numbers to a mobile or backup destination if the whole site is down.
What network settings does voice need?
A separate voice VLAN, QoS markings (DSCP EF for the audio) honored end-to-end on switches and routers, and enough bandwidth per call, about 80 kb/s each way for G.711 plus overhead. Low latency, jitter and loss matter more than raw speed. We test with live call quality measurements before and after go-live.
Teams Phone, hosted voice or an on-premises PBX?
Teams Phone suits organizations that already live in Microsoft 365. Hosted voice reduces equipment and maintenance. An on-premises PBX fits special integrations, analog devices or specific control needs. We compare cost, features, resilience and who administers it.
Can you build a custom IVR connected to our systems?
Yes. The menu can look up an account, read an order status or route a caller by data from your CRM or database through an API, and send complex cases to staff. We design the call flow with the people who answer calls today, and test failure paths such as a down database.
