Features in Release 2.2

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.
