    Skype calls disconnecting mid-call are commonly caused by connection quality or specific client issues.

    For Skype for Business, a poor or unstable Internet connection is the most likely cause of dropped calls. During a call, the connection indicator shows the quality (gray, yellow, or red). If the connection is slow or unstable, calls can drop. Recommended actions include:

    1. Improve the network signal
      • Prefer a wired Ethernet connection instead of Wi‑Fi.
      • If using Wi‑Fi, move closer to the router to improve signal strength.
    2. Reduce bandwidth usage
      • Close file-sharing apps, streaming services, and unnecessary browser tabs that consume bandwidth.
      • Use Task Manager (Windows 7 or later) to see which programs are using CPU, memory, disk, and network, and close nonessential ones.
    3. Check Internet speed
      • Run an online speed test or ask the ISP to verify download and upload speeds.
      • Compare results with the service level the ISP is supposed to provide; persistent low speeds should be escalated to the ISP.
    4. Update hardware
      • Old PCs, modems, or routers can cause slow performance even with a good line. Consider upgrading if all other steps fail.
    5. Check the other participant
      • Even if the local connection is good, the other participant’s poor connection can cause call quality issues or disconnections.

    If calls disconnect specifically when using Skype for Business or Lync 2013 with certain devices or configurations, there are known issues:

    • Outgoing calls can be disconnected when pressing the Spacebar or Enter key if a USB audio device (for example, a Polycom CX600) is paired. This happens because focus is on the hang-up button by default. Installing the May 12, 2015 security update for Skype for Business/Lync 2013 resolves this.
    • Calls made or accepted as an anonymous agent of a response group or as a delegate can disconnect if the server-side administrator configured a limited media port range and clients use ports outside that range. Installing the June 9, 2015 update (KB3054791) for Lync 2013 (Skype for Business) resolves this.
    • In Skype for Business Server 2015 environments, calls that are parked and then unparked can disconnect if the server is missing the June 2015 cumulative update 6.0.9319.55 and the Unified Communications Managed API 5.0 Runtime update.

    If the issue is with Skype (consumer) calls to mobiles or landlines not connecting or being blocked rather than dropping mid-call, ensure Caller ID is enabled, verify the destination is not in a restricted country, disconnect from VPN if in use, and ensure alternate contact info is set in the Skype profile.
