It really depends on how your system is designed.If you are vocoding all the calls from 8 or 13k voices to 16k and putting them in a PCM (so four in a TCH of 64k), you can calculate it. But some vendors like Lucent technologies is making a packet pipe against some 8/13k calls and putting them in a 2-16DS0 and using it towards the BTS.So it’s a vendor’s choice how to use the TCH for allocating the QCELP.
