<div>Hello,</div>
<div> </div>
<div>We have an asterisk 1.2.13 box that use a Digium TE205P T1 PRI connect to the telco, users mainly use snom 320/300 SIP phones.</div>
<div>When dialing to an external phone number with custom ringback music, users reported that they could not hear the music but can only hear the standard ring tone generated by the system.</div>
<div> </div>
<div>Is there any kind of settings need to allow the ringback music pass to the phone? We only use this simple dialplan to make outgoing call:</div>
<div> </div>
<div>exten => _9.,1,Set(CALLERID(all)=${CIDPREFIX}${CALLERIDNUM})<br>exten => _9.,n,Dial(Zap/g0/${EXTEN:1}||T)<br> </div>
<div>
<div>* CIDPREFIX is the 5 digit prefix of the company's PRI line, CALLERIDNUM are 3 digit internal numbers</div></div>
<div> </div>
<div>Thanks!</div>
<div>Vincent</div>
