VoIP Connectivity for Legacy TDM Equipment

Happy organizations. Adding VoIP access fast and easy.


Today, many organizations do not aim only migrating to the next generation networks, but also aim legacy equipment life extension. In addititon, these organizations would like to add VoIP services to their existing TDM network more quickly than would be the case if they upgraded their existing legacy TDM equipment. Many organizations now focus on which platforms to use.


Stillink VoIP Access Gateways are unique in many respects. One is that they support dozens of TDM signaling / protocol types such as SS No. 7, DSS1 Euro ISDN, QSIG, R1, R2, CAS, CIS, as well as VoIP protocols such as H.323 and SIP. Stillink VoIP Access Gateways may connect to any legacy equipment with any TDM signaling or protocol and provide VoIP connectivity.


The all-protocol switching capability and advanced routing features contained in Stillink VoIP Access Gateways represent a bridge between a legacy TDM equipment and VoIP network.

Stillink VoIP Access Gateways integrate both packet and circuit switching technology. A Stillink VoIP Access Gateway featuring an integrated gatekeeper and registrar/proxy/server provides an economical way for enterprises to manage a central database of phone numbers without the expense of a separate-box gatekeeper or registrar/proxy/server solution.

Furthermore, Stillink VoIP Access Gateways are with the TDM by-pass feature that operates not only for IP network failures but also for preselected routes. Alternate routing capability provides automatic fall back to the TDM if the IP network is unaccessible. Another advantage is that, enterprises may keep their present TDM connections while migrating to VoIP technology.
