Prerequisites and constraints of implementing the Split Registration Prevention feature

Last Updated : Oct 30, 2012 |

The main server and the survivable server, either SCS or SRS, must have Communication Manager Release 5.2 or a later release.

The main server and the survivable server must have an identical release of Communication Manager installed.

To administer split registration prevention, the following conditions must be met:

  • On the Systems Parameters Media Gateway Automatic Recovery Rule screen, set the Migrate H.248 MG to primary field to time-day-window. You can also set this field to either immediate or none when no other gateways are using the rules

  • After implementing the Split Registration Prevention feature, the BACKUP SERVERS IN PRIORITY ORDER column on the IP Network Region screen must have only one entry for the survivable server. The number of non-survivable server entries in this column is not affected.
