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.

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.

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.
