Failed calls while roaming

[WaseemLlama]

I have a dual-SIM Samsung smartphone.  SIM card no. 2 card for my pay-monthly contract with O2 UK.

During last few months I've noticed that no voicecalls to my O2 UK no. connect properly, in that I get no sound from the caller end, even though a call connection seems to be in place and the connect-time timer is constantly counting up!
I'm not sure whether the caller can hear me.

I'm very concerned that I'm being charged for calls that fail, as far as I'm concerned.

O2 must investigate this issue.  I'm prepared to have my device logged, if this helps the diagnosis.
