Bounty to be paid for Skype functionality for Asterisk

(- caryon - canceled - there is a commercial one I can use)

We will need a trustee if someone is only willing to pay anonymous.

Details:
There a two possible ways to do this.
Create a Asterisk extension,
1. with Skype low level functionality (reverse engineering)
2. on top of the documented Skype API (without running a skype Client)

Call quality should be equal to skype, also must include at least a linear pcm converter

In any case it has to work on linux as an additional module for asterisk.
Multiple account-login should be possible.

Note: Please consider the following limitations of the interface to the Public Skype API:
1. The Skype 'engine' requires X-windows to be running
2. Currently the audio stream cannot be directed at anything other than /dev/dsp.
3. Only one (asterisk) client can use it at a time.
4. Interface to the engine is via a specific version of DBUS

2 and 4 are planned to be changed in future, but in order to write a channel driver all of the above need to change. If you want Skype to consider changing it's API, then contribute here: https://developer.skype.com/wiki/NakedSkype

== compilation of information ==
  • Skype API information Skype-devzone
    • Skype for Linux public API is entering closed beta soon. It's based on D-BUS Skype-Forum Post
  • Skype API is now available as a beta, so can be theoracally integrated with a skype client runing on asterisk , you need to register to the skype forum, in order to get access to the beta.
  • Analyzes of the Skype protocol from the Columbia University Computer Science Department PDF
  • Method 2 isn't possible as mentioned above. The API is only provided by the running skype client via dbus. You can controll some client stuff via this dbus-api, you could write a chan_skype to place outgoing calls (shouldn't be that hard) but in order to get the audio stream you must either capture the stream written to /dev/dsp (skype only handles oss) with overwritten syscalls (read,write) and LD_PRELOAD or use an appropiate dummy-sounddevice. The API documentations explains that you can change the audio devices with SET AUDIO_IN/OUT, but that doesn't work at all. While this all requires a client running, the only possibility to apply for the bounty seems to reverse engineer the protocol and implement that into a channel driver.

== user thoughts ==

== Original Skype Linux API ==

== Try ChanSkype ==
  • Although not open source, ChanSkype is an option for those who are willing to pay a license per incoming or outgoing channel.

I recently had the idea to write the following skype daemon:

- the daemon starts on demand one (or more if needed) xvfbs that are a kind of null-x servers
- for each client session, the deamon starts one skype process. the process is set up to use the xvfb as x server
- a library is preloaded to the skype program that fakes a /dev/dsp (like esddsp, artsdsp or alsadsp do)
- the skype process is controlled over the skype api
- clients would communicate with the daemon via IPC
- there would be a library to communicate with the daemon used for both signalling and sound. an asterisk module would use only this library

Technically, although not ellegant, it would be possible i guess and it would work. The only problem is it would break the following eula points:

- we are not allowed to distribute software that uses the skype api (providing source code also probably means distributing i guess) unless skype allows us to
- we are not allowed to hide the damn gui

It's been done...

by Tim Hunt on Tuesday 31 of October, 2006 [13:27:49 UTC]
Take a look at http://www.chanskype.com.

It's not elegant, and each instance requires a Skype session, but multiple Skype sessions are supported using VNC.

Be warned that (as of 10/31/2006) Version 1.2.X does not install cleanly on a Trixbox type configuration but it can be made to work.

Skype2iax

Hi,

I'm currently developping it.
First beta will be released very soon.

Functionnalities are :
- Easy way to create Skype API, IAX and both protocols based apps in java.
- Skype To Asterisk call forwarding.


This solution uses a modified version of JSkype lib and IAXClient lib.

Skype device hints

by burdick0608 on Tuesday 31 of January, 2006 [19:09:27 UTC]
Now that there are skype devices hitting the market, maybe they could be a starting point. The netgear skype wifi phone (needs no PC) might just run linux itself?

Skype & Asterisk integration proposal

by Vitaly Repin on Friday 23 of December, 2005 [09:19:55 UTC]
There is a following possibility: skype (several instances) installed on the server-side and connection between this skype and asterisk. It will be possible to call skype users from any device connected to asterisk and to use SkypeOut in the same manner.

Benefints: 1. Skype installed on only one computer (some kind of DMZ) - security improvements. 2. Company shouldn't upgrade end-user devices to use skype. 3. It is possible to make some kind of accounting (of skype usage).

Is this capability intrested, guys? Are you ready to pay for this project?

The softphone http://www.jajah.com offers already jajah to Skype calling without having Skype installed. It supports SIP, IAX and POTS termination, too.

I'd like to take a crack at this
