Hi Trevor,
Thanks for your suggestion, it works by adding a Answer() in between!
However it will make everycall in the CDR become "Answered".
Later on I found that setting progressinband=no in sip.conf finally fixed
this problem!
Best Regards,
Vincent

Hello,
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.
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.
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:
exten => _9.,1,Set(CALLERID(all)=$ {CIDPREFIX}${CALLERIDNUM})
exten => _9.,n,Dial(Zap/g0/${EXTEN:1}||T)
Try adding an Answer between those two, just to see who is producing the
ringing. If you do NOT hear ringing but DO hear music, it's an asterisk
or snom problem. If you still hear ringing, it's your PRI.
Might also want to check in to the phone's manual to see if there's a
setting to enable early-audio.
Trevor
