Asterisk PBX setup & configuration
We design and deploy Asterisk-based phone systems that map cleanly onto how your business actually routes calls — then hand them over documented and hardened.
PBX & Voice Application Server
Asterisk is the most widely deployed open-source telephony engine in the world, and its flexibility is exactly what makes it easy to misconfigure. A dial plan that "works" in a demo can drop calls under load, leak toll fraud, or become impossible to maintain six months later.
We build Asterisk deployments the way an engineering team should: version-controlled configuration, a dial plan structured around your real call flows, and security applied from the first commit rather than bolted on after an incident.
Our Asterisk PBX engagement, in scope
SIP trunk integration
Connect your chosen carrier or ITSP with correct registration, codec negotiation, DTMF handling, and failover between trunks so a single provider outage does not take your phones down.
Dial plan engineering
A readable, maintainable dial plan built around inbound routing, time conditions, IVR menus, ring groups, and queues — designed so your team can reason about it, not just us.
Voicemail, IVR & queues
Auto-attendants, call queues with agent strategies, voicemail-to-email, and business-hours logic configured to match your operational reality.
Security & anti-fraud hardening
Fail2ban, SIP over TLS, SRTP media encryption, strong secrets, and dial plan guards against international toll fraud — the failures that cost businesses real money.

Either. We can deploy onto infrastructure you already own and control, or provision a cloud VM in your account. If you would rather not manage the box at all, our managed hosting retainer covers patching, monitoring, and backups after go-live.
