IP Phone Release Notes 2.2
Features in Release 2.2
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
Where
iSpecifies the multicast IP Address from which to receive an RTP stream.
pSpecifies the UDP port on which to receive the RTP stream.
Ensure that this is a number greater than 3100.
vIndicates the optional volume setting that controls the volume of the stream
(optional) 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.
Example: This example receives a multicast RTP stream from 239.0.1.20 on UDP port 21000 with the voice settings at
<AastraIPPhoneExecute>
<ExecuteItem URI =
Example:
This example receives a multicast RTP stream from 239.0.1.20 at UDP port 21000 with the voice settings as used in the previous RTP stream.
<AastraIPPhoneExecute>
<ExecuteItem URI = ”RTPMRx:239.0.1.20:21000”> <AastraIPPhoneExecute>
Note: Once the RTPMRx command in the URI is sent to the phone, it stops the phone from listening to any previous RTPRx or RTPMRx commands. The phone starts listening based on the most recent RTPMRx command received. This behavior also applies to the RTPRx:Stop and RTPMRx:Stop commands as well, but tbe “Stop” command does not enable any further listening.
