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.
1 NET_OBJ_REF Source AlphaCom station
2 UINT1 Codec type
AlphaCom level codecs
OBSOLETE, VALUE 1,2 and 3 SHOULD NOT BE USED
1. G.711u
2. G.711a
3. G722

Telecom level codecs (+9dB louder than AlphaCom level)
6. G.711u
7. G.711a
8. G.722
3 TEXT16 Destination IP address
4 UINT2 Destination IP port
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).



&000204 .ex_profile.flags.RTP_stream_man_reg = 0 (0x00000000)

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.

ex_profile.ip_config.ip_st_audio_group = 61002 (0xee4a)
ex_profile.ip_config.ip_st_audio_prog = 61004 (0xee4c)
