I have tested the CS voice call using 1 TCH/H channel in osmo-bts-trx using USRP B210 board and CS voice call was not successful. 
When I configure 2 TCH/H channel in the TRX then CS  voice call works fine. BSC commit version used  was " 87ef68eb33d463d8aad1511a272cbdb779f1ba19"
As per your explanation 1 TCH/H channel is sufficient for 1  CS  voice call( Mobile originated and Mobile terminated CS call). Please correct me if I am wrong.

Thanks and Regards,
Mrinal
