3845 Call-Manager-Fallback

[dtom]

We are running IOS ADVENTERPRISEK9-M ver 15.1(4)10 on a Cisco 3845.  We tried to enter command for call-manager-fallback but the commands are not accepted.  Here is what we normally see:

er-router#conf t

er-router(config)#call-manager-fallback

er-router(config-cm-fallback)#

However, on this particular router we see the following:

er-route2r#conf t

er-router2(config)#call-manager-fallback

er-router2(config)#

Any thoughts here?

Does both the routers have same memory, features like call-manager-fallback requires the apt amount of memory as per the IOS loaded.

That was it.  The router that did not work needed more memory added.
