Device Registration to Unregistered timeout

Kent Drugge

If I turn off or unplug a phone, call manager does not show the device as unregistered for about 30 seconds. If it was shorter, it would be nice.

So a few questions. Is this normal ?  Is this controlled by a system parameter ?  Is there a reason it takes this long, i.e. srst or ?  This is all rather new to me.  Thanks,

Note: I want the shorter timeout, since we have 7925s, when they go out of range and go unregistered, I have a voicemail that answers, explaining they are currently out of range. But this timeout just makes the call hang in no mans land while waiting to unregister. Maybe there is a way around this ?

I think the keyword you are looking for is "keepalive"

Was about to find a lot of information by googling "cucm device keep alive registration"

Yes, Thank you Sean,

Bear in mind that changing the keepalive setting is a clusterwide configuration, and you'll be generating more traffic because of that, if you lower the values.
