Webhook callback for company wide number

Hello @Phong Vu,

We have a production app (via API) where we can call a number and a web hook callback is sent. We use the following to set it up (Ruby):

    rc = RingCentral.new(RINGCENTRAL_CLIENTID, RINGCENTRAL_CLIENTSECRET, RINGCENTRAL_SERVER)
    rc.authorize(username: RINGCENTRAL_USERNAME, extension: RINGCENTRAL_EXTENSION, password: RINGCENTRAL_PASSWORD)
    r = rc.post('/restapi/v1.0/subscription', payload: {
        eventFilters: ["/restapi/v1.0/account/~/extension/~/presence?detailedTelephonyState=true"],
        deliveryMode: {transportType: 'WebHook', address: DELIVERY_ADDRESS, verificationToken: VERIFICATION_TOKEN},
        expiresIn: 604800
    })

The problem is, we get the callback only when calling RINGCENTRAL_USERNAME (which is a phone number). But we have our sales team responding to a office wide RC company phone number. When that number is called we do not get any webhook callback. What we have to do so that we get a web hook callback when someone calls the office wide RC company phone number?

Warm regards,
