<p class="MsoNormal"><span style="color:#1F497D">In order for CUCM to tell a phone to play ringback tone, CUCM must receive a ringing or progress indicator from the network. CUCM is probably not getting the indicator in this case. Some SIP debugs on the GW
for a working and not working call would probably show that. I suspect a flex issue.<o:p></o:p></span></p>

<p class="MsoNormal">We are having a regular but not always issue with a client, where they are not hearing the ringing when dialing outbound on calls. These are SCCP 6945s to UCM 9.1.2 SIP Trunked to CUBE and then handoff to at&t’s ipFlex service.<o:p></o:p></p>
