Re: [Opalvoip-user] Silence when dialing. How to fix?

Re: [Opalvoip-user] Some basic questions and comments about Set/Get Volume and MuteSorry, I should explain some more.
If to do call with SIP provider, all is OK, so I can listen to the real line ( long signals) after some small time.
=============
MesType=OpalIndProceeding
Proceeding. m_callToken=C3195e96f11
MesType=OpalIndMediaStream
Media stream audio in opened using G.711-uLaw-64k.
MesType=OpalIndMediaStream
Media stream audio out opened using G.711-uLaw-64k.
<long signals>
MesType=OpalIndAlerting
Ringing. m_callToken=C3195e96f11
----here call answered---
MesType=OpalIndEstablished
Established. m_callToken=C3195e96f11
================

If I do the same with AXON PBX, I see MediaStreams only after the call answered.
Before this moment I have silence in the PC Speakers.

About 2-3 years ago the same problem was with T38modem (have possibility to listen to the line in Voice mode).
I don't know how but Vjacheslav fixed it in his application.
It looks that we need something like pseudo- long signals to PC speakers in such situation (when no real media before the call answered). How to do?
This is a very common situation, and all SIP softphones typically use a pseudo-indication.

Dmitry.

  The simple question.
  For example Opal do:
  partyA = "pc:*";
  SetUpCall(partyA, command.m_param.m_callSetUp.m_partyB, token, NULL, 0, &options

  I listen to the silence before the other party answered.
  I want to "listen to the line": long signals, busy signals.
  How to activate? I don't see such function in the OpenPhone (at least with old versions I am able to compile).
  What to do?

  Best Regards,
  Dmitry.
