• QFlex uniquely resolves multi-vendor interoperability issues by utilizing pre-loaded adaptors with profiles for all major IP PBX vendors, core session border controllers, and application server platforms. This simplifies and reduces the time-to-market for service providers to deploy SIP Trunking services, cutting the interoperability time from months to weeks. This unique interoperability approach also allows enterprises to use supplementary services such as call forwarding, transfer, and music-on-hold in a multi-vendor PBX environment, across different branch offices
• Programming Languages: C++, C, PHP, Java Script
