softphone:兼容Python 3的软件电话，支持音频流

# Softphone A python 3 compatible softphone built on the [pjproject fork by malarinv, branch:py37](https://github.com/DiscordPhone/pjproject/tree/py37). To use the streaming capability, use an Audio Callback class that suits your needs. See `AudioCallbacks.py` for examples. For installation instructions, click [here](INSTALL.md). --- ## TODO - [ ] Fix the slight audio lag/delay when using Audio Callbacks for relaying audio between systems. - [x] Check if adjusting pj thread value helps on the lag like [here](https://github.com/malarinv/pjproject/commit/2757c5553b8b05196ffc3fbbf3c09e63d2d79c89). **Helped a little bit..? Not sure, can be a coincidence.** - [x] Clean up the code. - [ ] Write documentation for all functions. - [x] Add proper logging. - [ ] Add DTMF support. - [ ] Add call transfer support. - [ ] Fix and test incoming calls. - [ ] Do not force registration of both incoming and outgoing accounts. Make it optional. - [ ] Fix better error handling. - [ ] Fix error when phone hangs up before softphone does. - [ ] Fix error when phone is not answered and we reach voicemail. Softphone becomes unresponsive. - [ ] Create a [Pypi package](https://pypi.org/) to install via `pip install softphone`. - [ ] Add support for multiple simultaneous calls. --- ## Missing something? You can look for functionality from other projects and create a PR to get it added to this project.
