Re: IP phone keep ailive signal

Hi Fabian,

I remember wondering this same thing;

Typically, three times the keepalive period is required for a phone to discover that its connection to Cisco CallManager has failed. The default keepalive period is 30 seconds.If a Cisco IP phone has multiple Cisco CallManagers in its CallManager list, it progresses through its list of secondary and tertiary Cisco CallManagers.

From this good doc (provided kindly by Ajaz);

Hope this helps!

Rob
