CITELlink SIP Handset Gateways

The CITELlink SIP Handset Gateway is the world's first handset gateways to provide next-generation IP PBX and SIP interoperability for legacy PBX telephones across multiple vendor lines. The CITELlink gateway communicates in legacy PBX protocol to traditional telephone handsets and Internet Protocol and Session Initiated Protocol, to an IP PBX or a Hosted IP Centrex service, and performs the translation between the two simultaneously.

Enterprise customers can now take advantage of a significantly more cost effective and easier migration opportunity that provides the "freedom of choice" when deploying next generation IP PBX or Hosted IP telephony applications on their traditional telephone handsets, as well as increased scalability. The CITELlink gateway connects to legacy telephones using the existing telephone wiring and connectors. The telephones remain line-powered from the CITELlink gateway, and the advanced IP telephony features within the new IP PBX or Hosted IP Centrex service become available on the legacy telephones.

CITELlink SIP Handset Gateways are architected with standards-based communication protocols to ensure a seamless transition for legacy platforms and provide the necessary bridge to enable an easy migration to next generation IP and SIP applications.

Freedom of Choice

CITELlink unlocks the barriers of legacy PBX systems — giving customers the freedom to communicate — using the IP and SIP platforms of their choice.

Lower Cost of Ownership and Administration

With the CITELlink SIP Handset Gateway, businesses can save as much as 40 to 60 percent by retaining their existing investment in telephone handsets and associated wiring infrastructure, reducing the need for upgrades usually required to support IP telephony, and eliminating the need for retraining employees.

  • Single dialing plan
  • Bridged line appearances
  • CTI and hosted unified messaging
  • Seamless call control and conferencing
  • Shared voicemail and applications
  • Mobility and telecommuter support

Deploy Best-of-Breed, Right-Sized Systems

Customers can now scale their voice networks beyond the capacity of an existing platform, while retaining their legacy telephone devices. CITELlink provides users with considerable cost savings in matching the density requirements for small to large enterprise locations and the SIP platforms deployed, with multi-site connectivity. Customers can also mix existing legacy telephones with new IP telephones, as their IP telephony communications needs grow. CITELlink enables customers and resellers to immediately access new opportunities in emerging technologies with the most flexible solution available.
