Hello,
As far as I know CDR_RTC(call drop due to remote transcoder) doesn’t always mean it’s because of transcoder. It might be from transmission line or faulty TRX. We had high rate of RTC drops in some cells, found the solution with transmission guys. Abis allocation was wrong. Check your transmission/TRXs, I would say.
