Notes:
auto-delete
: Clears the PDN/call when the last VoLTE dedicated bearer goes down for P-GW, S-GW,
SAEGW, GGSN, and ePDG.
Calls will not be cleared when one of the calls in a multiple PDN scenario is a VoLTE PDN. When the VoLTE
PDN goes down, all of the other PDNs found for the same IMSI are brought down, which will bring down the
call automatically.
