What we build with OpenSIPS

OpenSIPS development is the work of turning this open-source SIP server into the routing brain of your network. We configure and script OpenSIPS for dynamic routing, load balancing, SBC duties and clustering.

It suits carriers, wholesale providers and ITSPs that handle heavy SIP traffic. We connect it to your billing, rate tables and media servers. You also get a control panel or API to manage routes without editing config files. Changes go through staging first, so live traffic stays stable.

  • OpenSIPS
  • SIP
  • SDP

What we offer

OpenSIPS development services we offer

Custom OpenSIPS builds

Script routing logic and add modules so OpenSIPS enforces your exact carrier and customer rules.

Dynamic routing & LCR

Route each call by prefix, cost or quality using drouting, so you protect margins on every destination.

Load balancing

Spread traffic across gateways and media servers, and reroute calls automatically when one fails.

SBC development

Hide your topology, normalize SIP headers and block abusive traffic before it reaches your core.

Clustering & HA

Share state across OpenSIPS nodes so a server failure or upgrade does not interrupt calls.

Consulting & support

Review, debug and upgrade existing OpenSIPS deployments, with ongoing maintenance when you need it.
