5i Series IP Phone Release Notes
RTP and Multicast RTP via XML
The IP Phones have new XML commands an Administrator can use with the
“
AastraIPPhoneExecute
” object. These commands allow the phone to send/
recieve an RTP stream to/from given multicast/unicast addresses (without
involving SIP signaling). The new XML commands to use with the
AastraIPPhoneExecute object in an XML application are:
•
RTPRx
(Receive (Rx) a Unicast RTP stream or stop receiving a Unicast/
Multicast RTP streams)
•
RTPTx
(Transmit (Tx) a Unicast RTP stream or stop transmitting a Unicast/
Multicast RTP streams)
•
RTPMRx
(Receive (Rx) a Multicast RTP stream)
•
RTPMTx
(Transmit (Tx) a Multicast RTP stream)
The phones support the following RTP stream format:
•
G.711 mu-law CODEC
•
20 ms packet size
Note:
If one of the previous commands is sent to the phone which is
already in a call, the phone places the current call on hold and the RTP
streaming commands are performed using a new audio path.
