An update about my issue is that SS7_smgd still not pass cause code IE from PSTN.

should it be the cause of the not flow of early media?

  My design is the following:

  SS7_smgd[asterisk]Zap-----backtoback-------EuroISDN[Mediatrix box]----Sip customers

  In this design I have a problem about early audio no passed from asterisk to Zap un the incominga cal from Zap.

  I am sure SS7_smgd passes "early audio" to Asterisk because if I connect a sip client directly to asterisk I get it.

  In extensions.conf I have for the calling incoming from zap and ongoing to SS7_smgd the following:
  exten => _X.,1,noop
  exten => _X.,n,Dial(WOOMERA/${EXTEN}|60|og)
  exten => _X.,n,Hangup

  Nothing special.

  On the mediatrix box, the audio is active, but nothing media arrives from ISDN PRI until the call get connected.

  So the only porblem seems to be Zap.

  Any thought on it?????

  Regards


  Rosario
