Is it possible to host telegram on my own server?
<p><a href="https://telegram.org/" rel="noreferrer">Telegram</a> is a cloud based chat service. All of their clients are open source. I was wondering if there's a way to host a 'private' telegram service on my own server. </p>

<p>If not, is there anything out there that can provide all or almost all features that telegram provides?</p>
