Flowroute (now part of Intrado) built its reputation as a developer-focused SIP provider. IPComms is built for businesses that need reliable SIP trunking with real human support, PBX expertise, and transparent per-minute pricing — no API skills required.
Flowroute was a great choice for developers building custom voice applications. But as it's become part of Intrado, many businesses are looking for a provider with better support and more PBX expertise.
Flowroute was built for developers who think in API calls and SDKs. If you're an IT admin running a FreePBX or Asterisk system, IPComms gives you straightforward SIP credentials and hands-on configuration help — no coding required.
Flowroute's support model leans heavily on documentation and ticket-based responses. IPComms provides real phone support with engineers who understand PBX configuration, call routing, and voice quality troubleshooting — for every customer.
Since Flowroute's acquisition by Intrado (West Corporation), some users have experienced changes in support quality and product direction. IPComms is an independent provider with a 24-year track record of stability and consistent service.
