Short answer
Split tunnelling can exclude one application from a VPN while others keep the required route. For phone use, define the specific exception and test Surfshark Bypasser on Windows with rollback; do not assume that exclusion improves audio.
Key verification: Verify the phone application route and the protection of other work separately.
Sources and limitationsSplit tunneling allows you to decide which applications use a VPN and which go out over the regular connection. For a phone workstation, it is used to test a specific exception without changing the route of the entire work. This guide proposes a test of Surfshark Bypasser on Windows with acceptance and return criteria.
Define the exception before enabling it
Note which application should exit via each route and why. Check your company's and clients' access rules: Excluding an app can change the egress direction and remove VPN coverage for its traffic. Don't make a general exception for the browser if it manages services that require the protected path.
If telephony works correctly with the current configuration, there is no demonstrated improvement to justify the change. If it fails, it first preserves a reference to the behavior. A split tunnel does not automatically fix microphones, permissions, or phone provider issues.
Documented options in Windows
The official Surfshark guide distinguishes Bypass VPN, which excludes selected applications or sites, and Route via VPN, which directs selected applications through the VPN. For applications, it allows you to select the executable and asks to reconnect after the change.
The scope of this guide is Windows with an active subscription. Do not extrapolate steps or behavior to mobile or macOS. Identify the executable your application actually uses and review the selection if an update changes its path or installs additional components.
Original test plan
| Test | What to check | Evidence |
|---|---|---|
| Reference without exception | Call and administrative access | Observed route and initial result |
| Telephone application excluded | Entry, exit and continuity of a test call | Result with time and configuration |
| Administration without excluding | Access to an authorized own service | Preserve the intended route |
| VPN disconnected | Allowed behavior of each application | Does not contradict access policy |
| Retirement of exception | Return to reference | Restored configuration and access |
It is a proposed matrix, not measured results. Use authorized test destinations and your own services that allow you to observe the connection. Checking an IP in the browser does not show the path of the telephone executable: observe each application with appropriate tools or ask the administrator for support.
Accept the change only if it fulfills both functions
Verify that calls maintain the required behavior and that administrative applications follow the agreed path. Repeat after reconnecting and restarting the station, keeping the rest of the variables the same. If you cannot demonstrate separation, do not submit the configuration as accepted.
Remove the exception when the result becomes worse or violates access rules. Avoid turning a one-time trial into a permanent configuration with no responsibility. Record reason, date, executable and review condition.
When does Surfshark fit
Bypasser may be relevant if you already need the VPN and a policy allows different routes per application. It does not guarantee to reduce latency or solve a choppy call. CallsIQ has not tested this workstation or measured audio quality with Surfshark. Sources reviewed on 4 October 2026.
