The Cisco Unified Mobile Voice Access (MVA) feature on Cisco Unified Communications Manager (CUCM) allows users to place calls through a mobile phone by calling a designated number and then entering a Personal Identification Number (PIN) and the desired phone number. After the user is authenticated and dialed digits are collected, the call is routed to the intended destination.
The two calling search space (CSS) configuration options that are significant in routing the second stage call are as follows:
Mobility User's Phone Device Level CSS: The CSS configured on the mobile device associated with the mobility user determines which partitions and calling search spaces the device can access. The device level CSS is used to route the call to the appropriate gateway or trunk that connects to the public switched telephone network (PSTN) or another CUCM cluster.
Phone Line Level CSS of the Mobility User: The CSS configured on the phone line of the mobility user determines which partitions and calling search spaces the line can access. The line level CSS is used to route the call to the appropriate remote destination profile, which contains the routing information for the second stage call.
The other options listed in the question are not significant in routing the second stage call. Here is a brief explanation of each option:
A. Remote Destination Profile Rerouting CSS: The CSS configured on the remote destination profile determines which partitions and calling search spaces the rerouted call can access. This option is not significant in routing the second stage call.
D. Concatenation of Remote Destination Profile CSS and Line CSS: The concatenation of the remote destination profile CSS and line CSS determines the calling search space used to route the rerouted call. This option is not significant in routing the second stage call.
E. Trunk or Gateway Inbound CSS: The CSS configured on the inbound trunk or gateway determines which partitions and calling search spaces the call can access. This option is not significant in routing the second stage call.
F. Calling Number Transformation CSS of the Remote Destination: The CSS configured on the calling number transformation of the remote destination determines which partitions and calling search spaces the transformed call can access. This option is not significant in routing the second stage call.
In conclusion, the two significant calling search space configuration options in routing the second stage call in Cisco Unified Mobile Voice Access feature on Cisco Unified Communications Manager are Mobility User's Phone Device Level CSS and Phone Line Level CSS of the Mobility User.
