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.
