Dear Joe,

Yes, we try to detect "silent calls" of two types: SDCCH and TCH.
If the network is requesting you to establish a channel and then not sending any meaningful information (SMS or call), we mark this even as a silent call.
Some false positives could occur in case of network errors, so trace analysis is needed.

Cheers,

LM
