Is it possible that your SIP client will read and write audio to memory stream? On our media server we have already voice stream encoded with G711 codec and we would like to connect to IP PBX and send voice from memory buffer. We would also like to receive incoming voice and write it into memory stream.

Yes - you can do everything you describe with our VOIP SDK. There are two ways to achieve your goal…

Method 1: Access the raw RTP media bytes for the phone calls.
See the EnableRawRtpPacketAccess() API procedure in the SDK help file documentation for more information.

Method 2: Use the Tx and Rx IVR phone line interfaces.
This is probably a better way to do what you want. You can pass memory/stream based media to the VOIP phone lines. You can also receive the media data from the phone lines to copy to your stream buffers.

The IVR APIs will also help you with automatic format and rate conversions too.

See the following APIs to get started:
