TelcoBridges [[H.248]] stack is inherently highly available since it is part of the [[TMG-CONTROL]] software. Therefore, if the H.248 stack fails, it will be restarted.

		+	* If the TMedia unit fails, the backup unit will takeover (moving TDM trunks and IP interfaces if necessary). [[H.248]] terminations will be re-allocated on the backup unit. [[H.248]] calls remain active.
