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.
