3rd party SIP device setting:


       1)The device type is "Third-party SIP Device (Advanced)”

       2)The device SIP Profile is set as “Standard SIP Profile for Mobile Device”

       3)The settings in the sip profile are set as below:

           Timer Register Expires (seconds)Required Field: 720

           Timer Keep Alive Expires (seconds)*: 120

          (Refer to Page 31 of

       4)SIP Station Keepalive Interval: 240

       5)Save and Apply

       6)UCM replies 240 for Expires for 3rd party SIP device register


Is that the expected, or the setting in the SIP profile should be respected?
