hi,
Try this command to simulate ring back tone :
voice call send-alert

You should look the MGCP messages between MGC and AS5400. I also wonder is that Province B send SDP-Body in SIP_Invite, this allows SIP early-media.

thank for ideas
- "voice call send-alert " : my configuration haved already
- "progress_ind alert enable 8 " : I added this command but nothing change , still no ring back tone.
- my network inluding H323 & SIP : only SIP (used Sip software client ) have no ring back , H323 everything OK .
I try to compare the Message GW --PGW : q931 :
province B : no ring back tone --> in q931 have no this "Progress Ind i = 0x8188 - In-band info or appropriate now available " , even i added progress_ind alert enable 8.
province A have above message --> have ring back tone
thank and Rdgr
