About this Gig
Is your business phone system unreliable, misconfigured, or just not built for growth?
I build secure, production-ready VoIP systems for small businesses, call centers, and remote teams using Asterisk and FreePBX so your calls route correctly, your system stays protected, and your team never misses a call.
What I will do for you:
- Asterisk PBX & FreePBX installation, configuration, and optimization
- Custom dialplan IVR menus, inbound/outbound routing, call queues, time-based rules
- SIP trunk setup with failover, DIDs, and extension provisioning
- Security hardening, Fail2ban, TLS/SRTP, firewall, and brute-force protection
- NAT, codec & QoS tuning for crystal-clear call quality on any network
- Full testing, troubleshooting, and documentation included with every order
Platforms & tools: Asterisk 16/18/20+ · FreePBX · SIP/IAX2 · AGI/ARI/AMI · Twilio · Telnyx · Vonage · Ubuntu/CentOS/Debian
To get started, I need: SSH access to the server, SIP provider credentials, and your dialplan requirements.
Message me before ordering. I'll review your setup and send a custom offer tailored to your exact needs.

FAQ
Do I need to have a server ready before ordering?
Yes, I work on your existing VPS or dedicated server via SSH. If you don't have one yet, I can recommend a suitable server spec based on your user count and call volume — just message me before ordering.
Which SIP trunk providers do you support?
I work with all major providers, including Twilio, Telnyx, Vonage, VoIP.ms, and any standard SIP-compatible provider. If you don't have one yet, I can help you choose the right one for your country and call volume.
How long does a typical Asterisk or FreePBX setup take?
A basic installation and configuration is usually delivered within 1–2 days. More complex setups involving custom dialplans, multiple SIP trunks, or IVR menus typically take 3–5 days. I always confirm the timeline with you before starting.
Can you work on an existing Asterisk or FreePBX system, or only fresh installs?
Both. I regularly troubleshoot, fix, and extend existing systems — whether it's a broken dialplan, a misconfigured SIP trunk, or a system that needs upgrading to a newer version of Asterisk or FreePBX.
Do you support cloud-hosted servers or only on-premise installations?
I work on both. Whether your PBX is on a VPS (DigitalOcean, Vultr, AWS, etc.) or physical on-premise hardware, the setup process is the same — I just need SSH access to get started.
How many extensions or users can the system support?
FreePBX has no hard limit on extensions, users, or call queues. The actual capacity depends on your server's CPU and RAM. I can advise you on the right server spec for your number of concurrent calls before we start.
Will I be able to manage the system myself after you finish?
Yes. I deliver full documentation covering your dialplan logic, extension setup, and configuration details. FreePBX also has a web-based admin panel that makes day-to-day management straightforward without needing command-line access.
