The difference is, Sip.js is a full sip stack written in JS, Verto is a lot smaller simpler stack to use. If you dont need SIP (and really most people really dont) when you have WebRTC. Verto greatly simplifies the calling. -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Thorsten Göllner Sent: Monday, February 1, 2016 8:12 AM To: 'FreeSWITCH Users Help' <freeswitch-users@lists.freeswitch.org> Subject: [Freeswitch-users] Verto vs. SIP.js Hi, I want to setup a Click-2-Call-Button for our website. Is there any significant difference between Verto-Mod and libraries such as SIP.js? I do not really understand the advantage of Verto (if there is any).
