I'm running a 2851 MGCP Gateway with 4 BRI to a FAX Server. For this I configured the isdn protocol-emulate network command on the BRI Interfaces. Altough I saved the configuration, the commands are not there anymore after a reboot and so the connections to the FAX Server are broken when the Router comes back up. Had someone made the same experience. Any idea why this happens. Is it be a bug?
