To register the ipAddress and portNumber dynamically on a per-call basis, applications must register by only providing capabilities that they support. Applications must react to CiscoMediaOpenLogicalChannelEv that gets sent whenever media is established. If any features are performed before applications react to CiscoMediaOpenLogicalChannelEv, the features may fail. If the applications do not respond to this event during the time that is specified in the Media Exchange Timer in the Cisco Unified Communications Manager Administration windows, the call may fail. For details on the interface changes, see Cisco Unified JTAPI Extensions, on page 249 To view the message flow for Dynamic CTIPort Registration Per Call, see Message Sequence Charts, on page 761 The ChangeRTPDefaults interface is not supported on CiscoMediaTerminal. Note The following new or changed interfaces exist for Dynamic CTIPort Registration Per Call: Interface CiscoMediaOpenLogicalChannelEv Extends CiscoTermEv getpacketSize() Returns the packet size of the far end in milliseconds. int getPayLoadType() Returns the payload format of the far end, one of the following constants: int getCiscoRTPHandle () Returns the CiscoTerminalConnection object on which applications must invoke the setRTPParams request. CiscoRTPHandle Interface CiscoRTPHandle getHandle() Returns an integer representation of this object, currently the Cisco Unified Communications Manager CallLeg ID. int CiscoProvider getCall (CiscoRTPHandle rtpHandle) Returns the call object with the rtpHandle that is associated with a specific terminal. If no callobserver gets added to the terminal at the time when the applications receive CiscoRTPHandle in CallOpenLogicalChannelEv, CiscoCall may be null.
