    We are using RTPTx command to transmit audio from a phone and RTPRx to play it on the other phones. This is working on all the phones, including 7921, 7925, 7940, 7941, 7945, 7960, 7965, 7970 and 7971, but it does not work on 9971. These phones, 9971s, do go to listen and receive mode (speaker/mute light turns on) but the audio just doesn't go through. All the other features of XML apps (menus, text, inputs, etc.) are working fine on these phones but there appears to be a problem with RTPRx and RTPMx URIs on 9971.  We tested it on UCM 8.0.

    I upgraded to the latest firmware, 9.0.3 and the problem stays.
     
    All phones are connected with the same switch port, same XML commands (CiscoIPPhoneExecute) and associated URI (RTPRx or RTPTx) are sent but 9971s are unable to broadcast or receive any audio.
     
    Is there any special permission or setting that may be new in these phones which can cause this?
