ASAI and Domain Control
return_ack | This parameter enables the ECS to acknowledge the request |
| made by the adjunct. It can be set to “yes” for |
| acknowledgement or “no” for no acknowledgement. The |
| default is “no.” |
priority_ | [optional] If present, a priority call is placed if the destination |
calling | is a local extension. If the priority flag is specified for an |
| |
| |
uui_info | [optional] If an ASAI adjunct provides UUI in a Third Party |
| Auto Dial, then the ECS stores that UUI with the call. |
| UUI from an Auto Dial Call will be sent in any ISDN SETUP |
| message for the call, in the Alerting and Call Offered Event |
| Reports, and in a Route Request, if one is made. |
| The UUI IE sent over an ISDN trunk can contain more data |
| than the UUI IE sent to ASAI. This happens when the ISDN |
| trunk group is administered with supplementary service |
| protocol other than B and the UUI IE Treatment is set to |
| “shared”. The UUI for ASAI is packed within the shared UUI |
| before it is sent over an ISDN trunk, and is unpacked at the |
| other end. |
| This is transparent to the ASAI adjuncts, with two exceptions: |
| 1. If the maximum size UUI allowed on the ISDN trunk is |
| exceeded, then the lower priority data items will be |
| dropped. Whether or not this means that ASAI UUI is |
| dropped depends on the priorities of the data items. |
| These priorities are administered on each trunk group |
| form. Each item stored in shared UUI uses two extra |
| bytes.Therefore, if the ISDN trunk group is administered |
| to allow a shared UUI length of 32 bytes then the ASAI |
| UUI will be limited to 30 bytes instead of 32. |
| 2. If a service provider, or customer equipment other than a |
| DEFINITY ECS (R6.3 or later) will be interpreting the |
| contents of the UUI IE, then the trunk group used to |
| place those calls should have its UUI IE Treatment set to |
| |
| the ASAI application, without change. |

| Digital Network (ISDN),’’ in Chapter 12, ‘‘ASAI and Feature |
| Interactions.’’ |
