Hi! What is the IE "Location" for CC Disconnect? Does CC Release have the same cause?
What is the number you are calling? Is it mobile from you network?
Seems you have problem at Core Network.
Please check related KPI's such as Drop RRC %, CS signaling SR%, number of System Nas signaling Release Cs.


Thanks and reps are appreciated.

Thank you Dude,

We solve, it is due to test number.
