Source note · Unified CM media resources

In Release 15, whether a call fails when no MTP or TRP can be allocated depends on the service parameters Fail Call If MTP Allocation Fails and Fail Call If Trusted Relay Point Allocation Fails. When these are not enabled, the call proceeds without the resource.
