RTP Recording and Simultaneous Playing (not supported on 51i)
The IP Phones now allow for RTP recording and simultaneous playing of an audio file via XML
Execute commands. An Administrator can use the RTP and multicast RTP commands (RTPTx,
RTPRx, RTPMTx, RTPMRx) with the “AastraIPPhoneExecute” object to initiate this feature.
The RTP and multicast RTP commands allow the phone to send/receive an RTP stream to/from
given multicast/unicast addresses (without involving SIP signaling). An Administrator can use the
following two options appended to the RTP commands for recording and simultaneously playing
of an audio file:
• mix - When appended to an RTP command, “mix” enables RTP recording and simultaneous
playing of an audio file.
• disableIcon - When appended to an RTP command, “disableIcon” disables the display of the
mixed call icons on the LCD of the phones.
Sending RTP
When a phone receives a request for sending RTP:
• and there is an existing call on the phone, no new audio session is created; the existing RTP
call (incoming or outgoing) is sent to the receiving party.
• and the phone is already in a 3-way conference, the request is declined.
• and there is no existing call on the phone, a new audio session is created and the RTP call is
sent to the receiving party.
The following scenarios assume that a request for sending mixed RTP is initiated.
Note: This feature is not supported on the 51i. Also, if the cordless
handset (CT) and the base phone are connected (Models 9480i CT and
57i CT), this feature is not supported.
