"isdn bind-l3 ccm-manager service mgcp" command is automatically missing from the isdn interface and all the phones are going down. This has been happening intermittently at several locations. When I re-issue the command, it works fine.
I had a similar issue with my config rewriting on its own for supporting a PRI of less than 24 channels. A temporary workaround that was given to me was once the gateway is up and registered remove the "ccm-manager config" command once you reconfig the idsn backhaul on your BRI. This is something i used because the CallManager was overwriting parts of my config rather than deleting the line entirely. Hope it helps till you find something better.
