This Registered Product listing confirms the basic interoperability which exists between Nortel’s Software Communication System (SCS) and the Third Party Product identified above.

All testing was executed by the Third Party Company using a Nortel SCS system. Test results were reviewed by Nortel. Test coverage includes basic communication and functionality only between a specific release of Nortel’s SCS platform and a specific version of the Third Party Product, both as identified above. Where a SIP interface is used, testing is focused on the compliance of the SIP communication between the two products to RFC 3261, RFC 3842, RFC 2833, RFC 3515, RFC 4235, RFC 3891, RFC 3263, and RFC 4662.
