  • Enhancement for Skype for Business

    In a Skype for business environment, the phone places the last dialed method for a contact either through SIP URI or Tel URI and dials via the same method the next time until it reboots to default SIP URI.

    A Skype for Business Client does this via a right click and then always dials the selected Number:
    On the VVX press and hold the contact for a while and see all the Numbers. Select the Number you want to dial from now on and it will remember the choice until the Phone reboots.


  • Web Sign In Using Skype for Business

    You can enable web sign in on the phone using the parameter feature.webSignIn.enabled. Once the parameter is configured, you can enable or disable web sign-in for your Skype for Business profile.
