Can we make call and register user without websocket URL

[ElectronMB]

--> Can we register the user without a websocket URL for example

Example:

Normally we use code like that for registration of users.

 const server = 'wss://domain_name:__port__'
    const options = {
      aor: `AOR`,
      userAgentOptions: {
        displayName: '__display_name__',
        authorizationUsername: '__username__',
        authorizationPassword: '__password__',
        transportOptions: {
          server,
        },
        uri: UserAgent.makeURI(`__URI__`),
      },
    }
    const user = new SimpleUser(server, options)

    try {
      await user.register(options)
      await user.connect(options)
    } catch (err) {
      console.log('💥💥💥 Registration or connection failed:', err)
    }

But I want to make registered users only with
"username", "password", "domain", and URI and without the wss(websocket) server URL.
I want to make a call using TSL & SRTP enabled for the call so how can we make these happen?
any code for the same?
