A Complete VoIP Media Processing Solution
The IPM-260 is a complete VolP media processing solution providing IP and PSTN interfaces to build next generation applications for both today's and tomorrow's networks. By combining these capabilities on a single board, the IPM-260 can eliminate a number of separate special-function boards, resulting in reduced inventory, increased over-all system density, reduced costs and improved time-to-market.

Enable Fast & Easy Integration
Enabling accelerated design cycles with high density and reduced costs, the IPM-260 is an ideal building block for scalable, reliable VolP enabled media processing solutions. With the IPM-260's comprehensive feature set, customers can quickly design a wide range of solutions combining PSTN and VoIP networks.
    Protect Customer Investment
The IPM-260 is based on the VolPerfectTM architecture, AudioCodes' underlying, best-of-breed, core media gateway technology for all of its products. The IPM-260 supports AudioCodes' API, which enables software download, provisioning and control. It was designed to maintain essential API backward compatibility in order to protect customers' investment in the development of products based on former generations.

Deliver feature-rich solutions
A broad selection of firmware-based media processing capabilities is available with the IPM-260 including: message record/playback, conferencing, voice coding, echo cancellation, fax processing and call progress tones detection. Each channel resource on the IPM-260 is universal and can perform media processing functions while utilizing full flexibility in endpoints.
