What is friPCfgSegSizeVoiceNotPresent?

Maximum frame size data packets are segmented into when no voice is active on the port, from 32 up to 4096 bytes, or 'disable' which means a 32768-byte size (effectively no segmentation); 'nc' skips it. The default is 'disable', since without voice there is no latency reason to fragment.
