Alexandr Dranchuk commented on ASTERISK-25227:
----------------------------------------------

After investigating tcpdump I found that OOH323 doesn't sent Progress Indicator field in Progress message, thus many equipment ignore media offered including audio announcements.
Progress Indicator field must preset according CISCO documentation I found at http://www.cisco.com/c/en/us/support/docs/voice/h323/22983-ringback.html#progresstones

Thus I've update 2 lines of code in ooq931.c at ooEncodeH225Message() function from commented:
   /*Add progress indicator IE 
   if(pq931Msg->messageType == Q931AlertingMsg || pq931Msg->messageType == Q931CallProceedingMsg)
   {
      msgbuf[i++] = Q931ProgressIndicatorIE;
      msgbuf[i++] = 2; //Length is 2 octet
      msgbuf[i++] = 0x80; //PI=8
      msgbuf[i++] = 0x88;
  }*/

to 

   /*Add progress indicator IE 
   if(pq931Msg->messageType == Q931AlertingMsg || pq931Msg->messageType == Q931CallProceedingMsg) */

   if(pq931Msg->messageType == Q931ProgressMsg)
   {
      msgbuf[i++] = Q931ProgressIndicatorIE;
      msgbuf[i++] = 2; //Length is 2 octet
      msgbuf[i++] = 0x80; //PI=8
      msgbuf[i++] = 0x88;
  }


and it's starts to works as magic. tested at company's equipment,
