VOIP AUDIO CONFIG

VAC (VOIP_AUDIO_CONFIG)		0x00AF	175	AMC 11.02
$VAC L101 U6 '10.5.11.32' W1234 W4322			Configure the IP audio parameters for station 101, G.711u to 10.5.11.32 port 1234, incoming audio to AlphaCom on port 4322.
$VAC configure the RTP audio stream for "RTP-stream station", to activate the audio the station must be called or controlled by $CONN etc. Note that RTP uses even port numbers, and RTCP uses odd port numbers. So it must be at least 2 between source and destination port. E.g. 2000, 2002 etc.

5	UINT2 (optional)	Port in AlphaCom for receiving audio from external source. (If port not specified streaming to AlphaCom is not possible)
6	UINT1 (optional)	MultiCast Ethernet port 0 or 1. If the AlphaCom system is set up for MultiCast this parameter specify the physical eth where the MulitCast rtp group and program conference should be transmitted. Default is unicast (value 2).

By default the RTP stream station is "REGISTERED" during system start up. If manual registration is needed the system flag "RTP_stream_man_reg" can be used. If set the RTP stream station is down until the first "$VAC" command is received.

Group Call and Program Conference

When the RTP-stream station is included in a group call or program conference the RTP stream is sent to the destination IP address as specified in param 3 of $VAC. The IP port used is the port specified for IP station Group Call and Program Conference.
