Overview:

The Dialogic IMG 1004 Integrated Media Gateway is a carrier-ready VoIP gateway that supports both media and signaling in a single chassis. It allows service providers to add new telephony services quickly, and gives them a clear migration path to an all-IP network. The IMG 1004 brings the value proposition of an integrated media gateway into the low-density (1-4 span) gateway market.

The IMG 1004 provides any-to-any voice network connectivity and can work in tandem with Dialogic’s IMG 1010 to deliver SIP services into legacy SS7, PRI, and CAS networks, as well as IP-to-IP transcoding and multimedia border element functions, such as SIP mediation for network edge applications. Its compact 1U design, integrated SS7 links termination and CICs, GUI-based management, and software licensing for in-service capacity expansion make the IMG 1004 an excellent option for VoIP.

The IMG 1004 also features the Dialogic Programmable Protocol Language (PPL), which allows rapid implementation of ISDN PRI variants and other signaling changes.

Features and Benefits:

Features	Benefits
Simultaneous support for PRI, CAS, and SS7 signaling, along with SIP and H.323	Provides a flexible, cost-effective platform that can evolve from TDM-IP to all IP
SS7 signaling, call routing, call translation, and IP transcoding supported in a single chassis	Can reduce complexity and administrative overhead for VoIP services, and allows on-the-fly voice coder conversion
Supports multimedia border element capabilities, including SIP mediation, topology hiding, and media transcoding.	Facilitates efficient operations between incompatible network elements in a service provider infrastructure
Supports up to 128 channels in a 1U chassis	Allows easy scalability to 128 channels in a small footprint
Wireline and wireless support, including ENUM and DNS	Enables fast connection time and lower phone charges because callers can connect to each other directly without using the PSTN
Carrier-ready design uses dual Ethernet network interfaces	Provides high reliability and service availability
Works with load balancers	Optimizes distribution of SIP traffic and improves scalability and fault tolerance
