Today (Nov. 2^nd, 2009), DONJIN officially launches the New SDK of Keygoe Multimedia Switch—Keygoe V2.3.0. This version integrates all the development experience of our global customers and partners, and the efforts of DONJIN R&D engineers in these years. Comparing with the old version, it is highly improved the function and performance.

1.       Support T.38 and telecom-class fax service with super large capacity

Keygoe V2.3.0 provides better support for T.38 and telecom-class fax service with super large capacity:

1）Optimize its support for T.38. Optimize its support for T.38 to make the fax service carrier can utilize good-quality IP network (for example, NGN, etc) to load fax service, which enhances the service flexibility.

2）Large capacity. Stably support the fax parallel from 480 channels to 2400 channels. The related index, such as system resource occupation rate, sending/receiving success rate and MTBF, can be improved more. 

2）Compatibility of fax machine. Provide supports for more G3 fax machine model.

2.       Provide more flexible SS7 service support

Keygoe V2.3.0 increases the transparent transmission function for SS7. This function support SPs to develop more services based on SS7 protocol stack. Besides utilizing the existing ISUP and TUP protocols directly, Sis can utilize the Keygoe transparent transmission function to develop the services based on MTPS2, MTP3, SCCP, TCAP and MAP protocols, etc.

3.       Optimize media processing ability

Keygoe2.3.0 optimizes the media processing ability, further decreases the system resource occupation rate and DSP load rate. SPs can provide higher capacity and better stability even if the system configuration isn’t changed.

4.       Add practical tool

The tools like API event monitor tool, SS7 event monitor tool, network diagnose/ detect tool, Interface mapping configuration toll, analog signal analysis tool and ISDN log analysis tool, etc, can provide more convenient and effective way for Sis to increase development and maintenance effects, and reduce development costs.
