This command defines the IP address of the CUCM that uses the MTP. 2. These commands define the registration of the MTP resources with CUCM. 3. These commands define the number and type of MTP resources the Cisco IOS serv- ices offer to CUCM. In this example, a software MTP of five sessions is defined. A software MTP does not require DSP resources on the router (a hardware MTP does). SIP IP Address Bind CUBE uses the IP address egress interface to populate the source address of SIP or H.323 messaging it originates. In many cases, this default behavior is the desired operation. However, you can bind the source address CUBE uses to a specific interface, such as a loopback, if needed. The bind capability is currently a global command only and therefore binds all SIP mes- saging (regardless of whether the messaging travels over the inside or outside interface) to the configured address. A future CUBE capability makes this configurable on a dial-peer basis SO that inside and outside traffic can be bound to individual addresses. Example 10-17 shows how to bind SIP messaging to a loopback interface address.

Example 10-18 shows how to configure CUBE to originate a SIP OPTIONS ping toward the SP on a global basis.
