How We Work

Flexible Engagement Models

Engage our Asterisk developers the way that fits your project — whether you need on-demand expertise, a fixed-scope build, or a dedicated team that works as an extension of yours.

Hourly / On-Demand

For evolving or short-term needs

Pay only for the engineering time you use. Ideal for troubleshooting, small enhancements, code reviews, or work where the scope is still taking shape.

  • Billed by the hour, no long-term commitment
  • Fast access to senior Asterisk expertise
  • Transparent time tracking and reporting
  • Scale hours up or down as needed

Best for: bug fixes, audits, and ad-hoc development tasks.

Fixed-Scope Project

For clearly defined deliverables

A fixed price and timeline for a well-defined build. We scope requirements upfront, then deliver against milestones with predictable cost and no surprises.

  • Fixed budget agreed before work begins
  • Milestone-based delivery and sign-off
  • Defined scope, timeline, and outcomes
  • Ideal when requirements are locked

Best for: migrations, integrations, and scoped feature builds.
