[Freeswitch-users] Verto - audio only between FS and client

Mon Mar 12 22:11:32 UTC 2018

We generate a token every time a user joins a session (which is developed using a server side scripting language) - it can only be validated once.

The token and the conference name is forwarded to a VertoJS client, which validates them using a REST API. If either of them is not validated the session fails.

Yes, that’s excellent documentation, thanks for reminding me of that.

How exactly did you use the tokens to ensure that people couldn’t invade other sessions, or was that not an issue in your context? ATM I have users connecting to conferences in the format of <conf_myname_token> as the conference name, but it’s proving quite tricky to keep track of, especially if someone logs on from two browsers. Ideally I’d like to just have users connecting to ‘nothing’, with the app transferring the channel to <conf_myname> (and no ability for the client to write their own code to force a connection to <conf_someoneelse>).

Rick, I take it you've been through this https://evoluxbr.github.io/verto-docs/tut/transferring-a-call.html

I'm fairly new to this too -  we used the concept of tokens and REST API to get the users in the right session. Set useVideo to false to keep it audio only obviously.

in the source code for the client.

At the moment, I have a rather elaborate system of using a randomly generated auth code, which the app server keeps in Redis, and adds to the name of the conference. But the complexities of this are proving problematic in my code.
