At the command prompt, type change trunk-group xxx, where xxx is the number of the trunk group. Press Enter.
In the UUI Treatment field on page 3 of the Trunk Group screen, select shared.
(Optional) In the Maximum Size of UUI Contents field, type a number from 32 to 128 as the maximum User-to-User Information (UUI) size. The default field option is 128 bytes.
You must administer the trunk groups to send the appropriate UUI size over connected networks. For example, if the public network supports only 32 bytes of UUI and you administer a number greater than 32, the network rejects the UUI.
On the Shared UUI Feature Priorities page, which is applicable when you select shared in the UUI Treatment field, assign numbers from 1 to 6, where 1 is the highest priority. You can use the default field options.
If you leave a field blank, the system does not send any information related to the field in UUI Information Element (IE). If the public network supports less than 128 bytes, you must determine which feature information to send in UUI IE and assign a high priority to the related field.
