When using MGCP with CUCM if there is a failed trunk, it realizes it's failed and jumps to the next trunk.
When using H.323 (my personal preference) if the trunk it choses does not work, it simply fails dropping fast busy to the end user - making the rest of the lines useless. Is there a command in the IOS to tell it to try the next trunk in a trunk list in the event of failure?
change this on CUCM
