These commands define DSPs on the router chassis to be used for Media Resources (specifically, in this configuration, for transcoding). 2. This command enables passing User-to-User Information (UUI) parameters via Generic Transparency Descriptor (GTD) from the SIP trunk to CVP. The series of commands starting here are the base (bootstrap) definition of the Tcl and VoiceXML scripts used by CVP for IVR control of the call. These are the same scripts used for CVP deployments on TDM PSTN gateways. This command points to the IP address of the local CUBE router itself (the IP address assigned to the GigabitEthernet0/0 interface) and defines transcoding resources under local control of CUBE. This is the incoming dial-peer matching all calls from the SIP trunk. 212 SIP Trunking 6. This is the outgoing dial-peer routing calls to the SIP proxy and on to CVP. The Dialed Number Identification Service (DNIS) of the call is translated to 71006 before sending call to CVP to trigger the appropriate service for the call. The IP address of the Cisco Unified Proxy Server (UPS) proxy is used as the session target for call setup. G.711 is used for all contact center calls. If the incoming SIP trunk call is G.729, this codec mismatch triggers CUBE to engage transcoding resources (defined earlier in the configuration) for the call. 10. Additional dial-peers to trigger some of the call and error control Tcl scripts that CVP uses on the gateway. 11. The dial-peer tag "888999" corresponds to the LABEL configured on the ICM. This label is known as the "Voice Response Unit (VRU) transfer label" and is returned to the CVP call serv
