Is it possible to configure an SRST router to map phones' mac addresses to static DNs?
The problem is that the phones are configured for extension mobility in normal operation. But, when the WAN link fails, users who are not yet logged in cannot do so. I understand this is expected behaviour.
Note:- Using CME SRST backup is not a desirable solution due to it involving a more complex configuration with 2 databases.
If the above mac based workaround is not possible, I would appreciate any alternative suggestions.
When a phone registers for SRST service with a Cisco Unified CME router and the router discovers that the phone was configured with a specific extension number, the router searches for an existing prebuilt ephone-dn with that extension number and then assigns that ephone-dn number to the phone. If there is no prebuilt ephone-dn with that extension number, the Cisco Unified CME system automatically creates one. In this way, extensions without prebuilt configurations are automatically populated with extension numbers and features as the numbers and features are "learned" by the Cisco Unified CME router in SRST mode when the phone registers to the router after a WAN link fails.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
