I am using CUCM v9.1.2 with VCS-C/VCS-E (X8.2.2) for remote and Mobile access.
As Software, I am using jabber 10.6.0 for Android.
I noticed after a short time (5 min) the Jabber client unregister from the CUCM without showing any message on the device. The sip device profile was configured as stated in the Technote below.
Are there any parameters to change/to take into consideration? or has anyone such behaviour encountered?
