Nortel Open Client Strategy


The Open Client Strategy (OCS) is a ground-breaking initiative by Nortel to enable deployment of industry standards based technology and allow interworking with Nortel Communication Server 2000 (CS 2000) softswitch, the Application Server 5200 (AS 5200) or Multimedia Communication Server 5100 (MCS 5100), .

Through this program, developers of VoIP technology can apply for specifications and licensing that will enable development of products that can interoperate with Nortel VoIP and Multimedia platforms.

Accepted applicants will be granted a license or notice and receive no charge access to a suite of Nortel specifications and interfaces. There are several unique suites of documentation and specifications available and 3rd party developers should make an application according to their product focus.

Developers who wish to review the SIP and related specifications for the MCS 5100 / AS 5200, should apply for a license and documentation suite for OCS - MCS 5100 / AS 5200.

Developers who wish to review the SIP specifications on the CS 2000 should accept a notice to apply for the documentation suite for OCS - CS 2000 SIP Lines.

Developers who wish to review the MGCP specification on the CS 2000 should apply for a license and documentation suite for OCS - CS 2000 MGCP.
