I also experienced some issue when initiating the voice/video call through Smart/Globe subscribers. No issues at all on the same networks by initating a call 10 times (call back 10 times).
It depends in some factors (obstruction, signal strength, distance from the tower, and voice call status) between devices.
Bihira lang lalabas “Service Unreachable” kaagad kung kaya.
Recieving calls from other networks to DITO is not sure, untested, if VoLTE calls is present.
