Fluchtkapsel<p>At work, I currently face the challenge of finding a Linux softphone I can use with a 3CX PBX.</p><p>With sipgate we used Linphone, which worked better than sipgate's Softphone or CLINQ apps. But with 3CX the best I could achieve is registering the softphone. With Linphone I can initiate calls but as soon as I pick up the connection gets terminated by the remote side again (at least that's what Linphone says).</p><p>I tried Blink, which at least doesn't terminate immediately. But I don't get any sound, on neither end. I can hear recordings originating from the PBX, though. The codec negotiation works, too, as I went through each codec individually.</p><p>With Jami and GNOME Calls I can't even register the softphone with the PBX.</p><p><a href="https://nerdculture.de/tags/voip" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>voip</span></a> <a href="https://nerdculture.de/tags/sip" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sip</span></a> <a href="https://nerdculture.de/tags/3cx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>3cx</span></a> <a href="https://nerdculture.de/tags/linphone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>linphone</span></a> <a href="https://nerdculture.de/tags/blink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>blink</span></a> <a href="https://nerdculture.de/tags/jami" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>jami</span></a> <a href="https://nerdculture.de/tags/gnomeCalls" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>gnomeCalls</span></a></p>

It's always enlightening to hear different perspectives on communication tools.<br><a href="https://hear-me.social/tags/Linphone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Linphone</span></a> Firstly, I appreciate the mention of Linphone. It is indeed a great tool, and I should have included it in my list. Linphone stands out for its versatility and strong support for various communication protocols, making it a robust option for both personal and professional use.</p><p><a href="https://hear-me.social/tags/DeltaChat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DeltaChat</span></a> is new to me, and I am eager to give it a try. However, I am curious: is it just another XMPP client, or does it offer unique features that set it apart? Generally, I prefer les feature-rich clients because I often use just simple text and voice communication. For my personal use case, XMPP is fine when it is compatible with TTS (Text-to-Speech). You're right that IRC and XMPP have their strengths, but I am always on the lookout for tools that I can offer to regular users.</p><p><a href="https://hear-me.social/tags/Signal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Signal</span></a> and Session are both backed by single entities but prioritize user privacy. Personally, I don't have enough experience to delve deeply into the pros and cons of Signal and Session. A significant limitation of Signal is that I can't build the app from source code, and as far as I know, there is no real way to run it on a server OS—it's only available on iOS, Android, and via Waydroid on Linux, with wayland GUI. At least Session is working on x86 architectures. In general, I think both are useful for mainstream users due to their familiar interfaces and ease of use. While Signal and Session do a good job with privacy, they may not be the most secure options, and they certainly don't rank high on the Free Software scale. Would you agree with my evaluation, or could you elaborate on your criticism?</p><p><a href="https://hear-me.social/tags/Matrix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Matrix</span></a> is designed to be decentralized and open, allowing users to host their own servers. This decentralization provides greater control over data and enhances privacy. Comparing Matrix to XMPP+OMEMO might oversimplify its capabilities, as Matrix offers advanced features like cross-platform interoperability and robust end-to-end encryption. It's open-source, and I haven't seen any obvious problems with it. Could you elaborate on your thoughts about Matrix?</p>
