Overview 7

Nortel Networks Confidential

The profile is added when a new domain is created in the MCP system.

Note: The profile name in the TELEPROF table on the CS 2000 side

must match the profile name in the PRODOMAIN table on the MCP

side. Otherwise, interworking between the MCP and CS 2000 will not

work.

Call Forward

Both the MCP and the CS 2000 support call forwarding. No extra

interworking considerations are necessary as call forwarding does not

interact across the MCP and CS 2000 domains, except to deliver a call

between the two domains.

Call Transfer

Call transfer works between the two platforms. The calls are transferred

because from each platforms view the other is just initiating a new call.

Ad Hoc Conference calls

There is no change in the conference application between the two

platforms. When an ad hoc conference call is made, the client

application that starts the conference controls where the conference

bridge is allocated. For example, if the conference call is made from a

client application on the MCP side, the conference bridge will be

allocated on the MCP.

Media Negotiation

The MCP provides media negotiation for the CS 2000 since the CS

2000 gateway controller is not capable of providing this function in the

current release.

The MCP requires a list of all commonly supported codecs across the

CS 2000 media gateways to be provisioned in the cs2k.xml file. The list

is required because the MCP does not determine which gateway the

CS 2000 will use.

Although the MCP also allows for the provisioning of packet times that

the CS 2000 will use, this is not recommended. By provisioning specific

packet times, the SDP packet time will no longer pass transparently

through the MCP. This means that the packet time negotiation that

would normally occur at the client level is now being handled at the

server level, and this could lead to voice connection issues.

The SDP sent by the CS 2000 media gateways is only guaranteed to

contain the v=, c=, m=, and a= SDP headers in the SDP message. The

gateways can accept reception of other SDP parameters, so no

screening needs to be done on the SDP that the MCP sends to the CS

2000. The only exception is the screening of the m= lines to only
