Core Issue
This issue relates to Cisco Unity version 4.2(1) and TAPI Service Provider (TSP) version 8.1(3). For some reason, the IntergrationID in the Cisco Unity Telephony Integration Manager (UTIM) on the Primary Unity server was 0, yet the switch ID for all of the subscribers is 2, as is the IntegrationID of the Secondary Cisco Unity server.
Resolution
In order to resolve the issue, complete these steps:
Confirm from the Subscriber table in the SQL Enterprise Manager that the subscribers use the default SwitchId of 2.
Choose Start > Programs > Unity > Manage Intregrations in order to check the value of IntegrationID for the Cisco CallManager integration in the UTIM.
Ensure that this is 2 on both the Primary and the Secondary Cisco Unity server. If it is not, then use the button on the Integration window in the UTIM, provided in Cisco Unity version 4.2 and later, in order to change it to match the Switch ID in the Subscriber table.
