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
