I am now looking for voip solutions. And found information about Voip sdk.
According to their website (http://www.voipsipsdk.com/)
Voip sdk is based on IETF standards (SIP, STUN, etc.), so it should be compatible with other standard based products such as Asterisk, OpenSER other.

They have all features I need:
# Dynamically loadable codecs
# Registrar support
# Play wav files into conversation
# Record conversation into file
# Hold/Retrieve call
# Forward Call (Blind Call Transfer)
# Transfer Call (Attended Transfer)
# Mute Sound
# VPN support
# Noise reduction
# Auto gain
# Jitter buffer parameters
# Samples on Delphi, C#, VB, VB.NET, C++ 2005, C++ 6.0, HTML (SIP ActiveX)
# Windowless samples on C++ and .NET
# DTMF
# Adaptive silence detection
# Adaptive jitter buffer
# STUN support
# Comes as ActiveX control

But before I will download the evaluation version I would like to hear other people experience.
