According to Erlang history, the main purpose of this language is telephony systems. I found that there are lots of related modules such as ASN.1 parser and Diameter. But I didn't find any SIP module in Erlang/OTP official libraries. It's hard to imagine a programming language that developed for telecom purposes and doesn't offer a module for the most useful telecom protocol such as SIP. </div><div><br></div><div>So my question is why Erlang/OTP doesn't provide an official SIP stack? I found NkSIP but it seems it doesn't maintain anymore.</div><div><br></div><div>Regards,</div><div>Ali</div></div>
