| 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 $CONN etc. Note that RTP uses even port numbers, and RTCP uses odd port numbers. So it must be at least 2 between source and destination port. E.g. 2000, 2002 etc. Often used together with IP Dummy Station. | ||||
| 1 | NET_OBJ_REF | Source AlphaCom station | ||
| 2 | UINT1 | Codec type AlphaCom level codecs OBSOLETE, VALUE 1,2 and 3 SHOULD NOT BE USED 1. G.711u 2. G.711a 3. G722 Telecom level codecs (+9dB louder than AlphaCom level) 6. G.711u 7. G.711a 8. G.722 | ||
| 3 | TEXT16 | Destination IP address | ||
| 4 | UINT2 | Destination IP port | ||
| 5 | UINT2 (optional) |
Port in AlphaCom for receiving audio from external source. (If port not specified streaming to AlphaCom is not possible) | ||
| 6 | UINT1 (optional) |
MultiCast Ethernet port 0 or 1. If the AlphaCom system is set up for MultiCast this parameter specify the physical eth where the MulitCast rtp group and program conference should be transmitted. Default is unicast (value 2). | ||
By default the RTP stream station is "REGISTERED" during system start up. If manual registration is needed the system flag "RTP_stream_man_reg" can be used. If set the RTP stream station is down until the first "$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.
