Applies to Cisco Jabber for iPhone and iPad.
We deprecated this parameter as of August 2020 because of changes in Apple Push Notifications (APNs). We have closed the VoIP
Specifies if Jabber uses the VoIP sockets to set up SIP connection with Cisco Unified Communication Manager server. Even if
Jabber is inactive, Jabber refreshes the keep alive timer parameter to re-register the Cisco Unified Communication Manager
server to keep SIP registered through the VoIP sockets.
If you're using APNs, Jabber users will always receive calls in Jabber even if their Jabber app is inactive. If you're not
using APNs, then set this parameter to true to ensure Jabber users receive their calls even if their app is inactive.
Jabber will be registered in the Cisco UC Manager device page until the TCP connection times out by iOS.
true(default) —VoIP sockets and keep alive timers are enabled to ensure Jabber will receive calls even if it's inactive.
false—VoIP sockets and keep alive timers are disabled. We recommend you only set the value to false if APNs are enabled. Otherwise,
if you set this parameter to false, the SIP connections with Cisco Unified Communication Manager close after a short period,
which is controlled by the operating system, and Jabber becomes inactive.
Cisco Jabber will automatically sign users out if the parameter value is changed.
