Browser not asking for microphone using sip card

[Dronedale]

Hi everyone,

i am trying the past couple of days getting the SIP card to work. I´m using duckdns for https. After configuration of my SIP card and start making a call, nothing happens (it just says 'calling' and i cannot hang up)
As far as I know I should be asked by the browser for mic access, but this is not happening in my case.

the browser log says:

'Connecting to wss://:8089undefined/ws', which fails (invalid arg exception)

I think 'undefined' shouldn´t be there?

here my config:

`type: custom:sipjs-card
server: 192.168.178.2
port: '8089'
video: false
ringtone: /local/asterisk/ringtone.mp3
button_size: '62'
custom: []
dtmfs:

• name: Door
  signal: '1'
  icon: mdi:door
  extensions:
• person: person.daniel_schroder
  name: Daniel HA
  extension: '100'
  secret: 123456
  icon: mdi:monitor
• person: person.doorbell
  name: Doorbell
  extension: '101'
  secret: 123456
  icon: mdi:tablet
• person: person.test
  name: fritz
  extension: '102'
  secret: 123456
  icon: mdi:tablet
  state_color: false
  ringbacktone: /local/asterisk/backtone.mp3
  auto_answer: false
  custom_title: ''
  hide_me: true
  `

Any suggestions?

Looks like your missing the prefix option. Try adding prefix: '' to the card config.

Thanks for your quick response! Tried it and it is working.
Why do I need to set this parameter in the config while your default config does not contain it?
