Unicoi Systems is proud to announce the release of Fusion Embedded SIP version 5.2. With this release, Fusion Embedded SIP provides support for the OPTION server authentication method, along with API updates to accommodate customized SIP headers.

The code improvements to Fusion Embedded SIP 5.2 render a more adaptable development option. The API supports custom headers, which enables a broader range of RFCs. Support for server authentication is included, via the OPTIONS request, which provides feedback on external SIP devices. This latest version of Unicoi’s SIP solution also uses smarter request routing to provide better connectivity to distributed SIP domains. Other code improvements include redundant code reductions resulting in a small overall footprint and improved maintainability.
