Using RTP and Multicast RTP Commands
The IP Phones have RTP and Multicast RTP XML commands that 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 RTP and
Multicast RTP XML commands 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.
