Hi Lochinvar,

I believe you are referring to this setting

The RNA Reversion Timeout is available (to pullback and re-distribute calls) to the next available or idle Agent. This setting is done at the Line Group level.

RNA Reversion Timeout

Enter a time, in seconds, after which Cisco CallManager will distribute a call to the next available or idle member of this line group or to the next line group if the call is not answered and if the first hunt option, Try next member; then, try next group in Hunt List, is chosen.The RNA Reversion Timeout applies at the line-group level to all members.

Under "Line Group Configuration", you can find (and change) the "RNA Reversion Timeout" (which is by default set to 10 seconds)

Hope this helps!

Rob
