Reliable business phones, clean call routing, and vendor coordination – without you living on the phone with the carrier.
F3 Tech Services designs, installs, and supports business VoIP phone systems for Dallas small businesses, law firms, medical practices, and professional offices. We handle everything from planning call flows and auto attendants to coordinating with the VoIP provider, porting your numbers, provisioning handsets and softphones, and maintaining the system.
This page explains what our VoIP services include, who they are for, how we handle vendor relationships, what a typical deployment looks like, and why a professionally designed phone system is more stable than a do it yourself setup.
When phones cut out, voicemail does not route correctly, calls ring in the wrong place, or your team loses confidence in the phone system, the entire office feels it.
Most VoIP disasters are not caused by the underlying service. They come from:
Our job is to make phones boring again – stable, predictable, and easy to live with.
Our VoIP work is focused on organizations that rely on phones to communicate with clients, patients, and partners, such as:
If dropped calls and confusing call paths are a recurring theme, we are a good fit.
Your phones live on top of your network, servers, and cloud stack. If you want the entire environment managed – not just the phone system – our Managed IT Services cover endpoints, security, backups, and network health.
Softphones and mobile VoIP clients depend heavily on WiFi. If your wireless network is weak, your phones will be too. We design and deploy business grade wireless for reliable roaming and call quality.
VoIP projects vary based on number of users, locations, and complexity, but most engagements fall into these ranges:
| Environment | Typical Budget | Notes |
|---|---|---|
| Single office, up to 10 phones | $1,500 to $4,000 (project) | Design, setup, and porting assistance |
| 10 to 30 phones or hybrid staff | $4,000 to $9,000 (project) | More complex call flows and routing |
| Ongoing support and changes | $250 to $750 per month | Moves, adds, changes, and vendor liaison |
Carrier service fees and handsets are separate and depend on the chosen provider and device mix.
We follow a structured VoIP onboarding process so that nothing is missed and cutover day is boring instead of stressful.
We document your current phone usage, numbers, extensions, departments, hours, and pain points. We design the target call flows and auto attendants and review them with you so expectations are clear.
We coordinate with the VoIP carrier to create accounts, configure trunks, and start porting requests. We gather any required documentation and monitor the porting process, scheduling cutover windows that minimize disruption.
We provision handsets, softphones, and mobile apps. We prepare the network for voice by reviewing switching, PoE, VLANs, and QoS. We install and test devices before go live.
On cutover day we move traffic to the new system, verify inbound and outbound behavior, and validate call flows. We train staff on using the phones and softphones. We remain engaged during the first weeks of use to catch issues and refine behavior.
Most small office deployments take 2 to 4 weeks from discovery to stable cutover, depending on carrier porting timelines and hardware availability.
No. In most cases we port your existing numbers so clients keep dialing the same numbers they already know.
Yes. We can work with your providers to maintain specific analog lines where required while moving voice traffic to VoIP.
We are based in Dallas and focus on the DFW area, but many clients have remote staff or additional offices in other cities. We can support those as part of a unified phone system.
We work with you and the carrier on failover options such as forwarding to mobile devices or backup lines, based on your risk tolerance and budget.
Let us design and deploy a VoIP phone system that supports how your office actually works – and remove vendor battles from your daily life.
