Hi… Any suggestion in one of the cell site Csfb calls are getting blocked when preferred mode selected as lte
Manual mode to GSM calls are getting through
Don’t lock the phone to LTE in TEMS
It’s in auto mode
On what stage is the call getting disconnected? .Also, on call location update needs to be done successfully by ue and mss over SGs intetface.
Are LTE and GSM nodes on different mss?
Same. When in LTE mode trying to do a circuit switch call… It should fall back to 2g network… But here Csfb getting blocked
What is the solution for pmrrcsecfailintegrity
Can u please share snap of events
Please check csfb Switches in site
Csfb switches are On…
Is MT working?
Yes, MT is working
Ok, please check manual voice call in dual network mode.
Is it working.?
Manual also not happening
Ok, please check csfb policies. You may also check blind handover switch.
Check the cell GSM or eNodeB
