Description (partial)

Symptom:
Based on the supported SRSV topologies section in the CUC SRSV reference guide, it doesn't specify what integration methods of CUC should be used.

The issue is that not all integration methods are supported for the various SRST options.

We have internal documentation that states the following integrations are expected configurations.
SRST (call-manager-fallback) only supports a SIP integration with CUC.
CME-SRST (telephony-service) supports both SCCP and SIP integrations.

Conditions:
Unity Connection SRSV
IOS SRST or CME-SRST integration
