How to Use Multiple DIDs for concurrent outbound Calls

[Engineerumair]

These are typically directed to the google group.

I have an application that run campaigns and call customers of each campaign. I have one On Sip user and 4 DIDs purchased from OnSip and I would like to assign those DIDs to call those customers using those DIDs.

I want when customers are called from campaign1 the DID1 should be used and similarly for other campaigns.

I don't know how can I make concurrent calls using those DIDs with one user.

Is there a way I can use DIDs concurrently / Parallel without creating more users?

This is not an issue with the sip.js library.
