Multicast audio for PA system http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=8120954 2013-05-19T23:48:45Z 2013-05-19T23:48:45Z YANIS SAUVE http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=8153149 2012-10-30T17:01:06Z 2012-10-30T17:01:06Z

I got it to work as I supposed it's intended. But that won't work for me, because as soon as the multicast command passes, the phone open a channel, and when there is no sound, I still hear a hiss in the speaker.  Not really what I wanted.  I would've liked the phone to stay silent, and open it's speaker only when there is something broadcasted on the multicast channel. Thanks a lot for the suggestion.  I hope this thread can help somebody else.

I think in general your plan should work.  See the 'Interaction with Call Streaming' section for details on how it works with normal call operation. Note also you can take advantage of the 'Idle URL' functionality, which will cause the phone to retrieve a URL (which you can then have trigger your streaming service) after a configurable idle period.

Hello everyone, Here's my setup:  CUCM 7.1.2, SCCP phones, using a Cyberdata V3 Paging Server (SIP). I'm using the paging server by dialing it's DN, and then it multicasts audio to SIP Speakers for paging purposes. Is there a way to have the phone continually listen to the same multicast IP:port? I've come across RTPMRx with CiscoIPPhoneExecute. By using this, will the phones continue to listen for the multicast stream even if it's not used, all this without disrupting phone functionality? My plan would be to have a machine send the HTTP POSTs to the phones periodically to keep them listening, or is there a way I could include the relevant commands in the XML config file so they start listening each time they reboot? Thanks   [color=#525252][/color]
