omnibrain 14 Posted July 7, 2022 (edited) I'm currently looking to integrate softphone functionality into our software. I'm looking for VoIP/SIP SDKs/components. 2 years ago I alreay tried (and even bought) Delphi SIP components but ran into trouble when the other side hanging up did not get registered correctly. I raised the issue with the developer but he soon stopped responding. It was easy to use, but at the same time rather limited. Now I found VoIP SIP SDK - ABTO Software's VoIP SIP SDK and VoIP SDK, SIP SDK for creating audio, video, and IM Apps (portsip.com) and VoIP für Unified Communications | GlobalIPTel and VaxVoIP SIP SDK - Develop SIP Softphone, webphone, video conferencing, audio conferencing, SIP Server, IPPBX, web dialer, SIP Tunneling Server, Call Recording Server, and IP-Telephony services. and SIP SDK for Windows (mizu-voip.com) Has any of you experience with either? Or can anyone recommenend another SDK/component? My first goal is to implement a softphone client with call recording and possibly audio playback. It should also be able to receive/decode DTMF tones. Possibly later I want to implement DIN CLC/TS 50134-9 "Social Alarm Systems" Edited July 7, 2022 by omnibrain Share this post Link to post
