Hello IMS Experts.
I am getting VoLTE drops with SIB Bye in DL cause “insufficient bearer resources”.
From RF point of view all is OK on both side UEs.
Then what is the resource that is insufficient? Transport maybe? Or what?
Is eNB ok?
This error means SGW request eNB to establish resources and eNB said nope no can do.
How do you check SIP Bye Drop reasons?
