Additional Features

Group RTP Paging (receives RTP streams)

You can configure the phone to allow it to receive a Real Time Transport Protocol (RTP) stream from pre-configured mul- ticast address(es) without involving SIP signaling. This is called Group Paging on the IP phones. You can specify up to 5 multicast addresses that the phone listens for on the network. This feature is configurable using the Aastra Web UI only.

The 6735i in the local network listens for RTP on the preconfigured multicast address. The Phone displays the “Paging” message to the phone’s LCD. It uses the G711 uLaw CODEC for multicast RTP.

The recipient can drop the incoming page if required. The recipient can also set Do Not Disturb (DND) to ignore any incoming pages.

For incoming RTP multicasts, the ringing display is dependant on the setting for the “Allow Barge-In” parameter. (See “Allow Barge In” on page 181.) If this parameter is disabled, and there is no other call on the phone, then the paging is automatically played via the default audio device.

If there is an existing call on the phone, the call initially displays in the ringing state. The user has the option to accept/ignore the call. If the “Allow Barge-In” parameter is enabled, the RTP multicast call barges in, and any existing calls are put on hold.

If an RTP multicast session already exists on the phone, and the phone receives another incoming RTP multicast session, the priority is given to the first multicast session and the second multicast session is ignored. The behavior for the incom- ing calls in this case is also based on the setting for the “Allow Barge-in” parameter. The incoming call is handled as if there were an existing call already on the phone.

Configuring Group RTP Paging

Aastra Web UI

Use the following procedure to configure RTP streaming on the receiving end for Paging applications using the Aastra Web UI.

1.Click on Basic Settings->Preferences->Group Paging RTP Settings.

2.In the “Paging Listen Addresses” text box, enter the multicast IP address(es) and port number on which the phone listens for incoming multicast RTP packets.

Enter the IP address in dotted decimal format. (for example, 239.0.1.15:10000,239.0.1.20:15000) You can enter up to 5 listening multicast addresses.

If this field is blank, the Paging Listening capability is disabled on the phone.

Notes:

1.Recipient of a Paging call can set a global “Do Not Disturb” (DND) to ignore any incoming pages.

2.For incoming Paging, the phone uses the Intercom configuration settings. The incoming Page is dependant on the “Allow Barge-In” parameter setting and the “Idling/On Call” state.

3.Click Save Settings.
