4.4.3 RTPMRx
The RTPMRx URI instructs the phone to receive a Multicast RTP stream. The RTPMRx format to
use with the AastraIPPhoneExecute object in the URI is:
RTPMRx:i:p:[v]:[mix]:[disableIcon]
Where
• i specifies the multicast IP Address from which to receive an RTP stream.
• p specifies the UDP port on which to receive the RTP stream. You must ensure that this is
a number greater than 3100 to make sure not to use a port already bound to the phone.
• v (optional) indicates the optional volume setting that controls the volume of the stream
playout. The supplied value is an offset to the current volume setting. After the initial
volume level gets set and the stream starts, you can manually change the volume level as
required using this “v” option. If you do not specify the optional volume parameter, the
phone uses the current volume setting on the phone as the default.
• mix (optional) specifies that the incoming RTP stream will be added to the existing audio
stream if it exists.
• disableIcon (optional) specifies that the “mix” icon is not displayed (if “mix” is configured in
the command).
