resolution of MSCs for Single Radio Voice Call Continuity (SRVCC).
Usage
This feature requires that a valid SRVCC license key be installed.
Use this command to configure the context ID for the DNS lookup.
MSC selection using DNS takes precedence over locally configured MSCs. If DNS lookup fails, the MME
will select the MSC from local configuration.
DNS based MSC selection can be defined for an MME service, or for a Call Control Profile. Both
configuration options specify the context in which a DNS client configuration has been defined.
Configuration via Call Control Profile takes precedence in cases where DNS selection is also configured in
the MME service
