Next, you define the SIP profile (see Figure 12-11). Fill in the values as follows for "Name" and "Description," respectively, and then click Save: Name: CUBE SIP Trunk Profile Description: SIP Trunk to CUBE Profile Step 6. Now you need to create a device pool in the CUCM. Device pools are used to define sets of common characteristics for Unified Communications (UC) devices. When a user in Branch1 moves to Branch2 and calls via SIP trunks, the CUCM must know characteristics of that device. The device characteristics you can specify for a device pool are Region, Date/Time group, Cisco Communications Manager Group, and Calling search space for auto-registration. Step 7. Before you can define the device, Figure 12-12 and Figure 12-13 show how to configure a region and device pool. Note that the bank decided to create a Region that would use G.729 codec within the region and with other regions to make the outbound and inbound calls.
