Description:	It would be very useful if the console phone could optionally operate with audio in one direction only. A configuration option such as "noaudiocapture=yes" in alsa.conf (and oss.conf for oss users) would permit the console phone to operate with a PA system to provide a external pager facility while still allowing pcm capture to be used for live music on hold. ****** ADDITIONAL INFORMATION ****** This functionality would require changes to chan_alsa.c (similarly chan_oss.c) to prevent the grabbing on module load of the pcm capture stream e.g. snd_pcm_open(&handle, ALSA_INDEV, SND_PCM_STREAM_CAPTURE, SND_PCM_NONBLOCK) and to feed muted audio to asterisk e.g. f.frametype = AST_FRAME_NULL;
