Using RTP Recording and Simultaneous Playing
(not supported on 51i)
The IP Phones 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.
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.
