TODO

• Fix the slight audio lag/delay when using Audio Callbacks for relaying audio between systems.
• Check if adjusting pj thread value helps on the lag like here. Helped a little bit..? Not sure, can be a coincidence.
• Clean up the code.
• Write documentation for all functions.
• 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 to install via pip install softphone.
• Add support for multiple simultaneous calls.
