RTC_E_STATUS_INFO_CALL_FORWARDING
RTC signaling reports that the call is being forwarded
RTC_E_STATUS_INFO_CALL_FORWARDING is HRESULT 15663285 (0x00EF00B5) from RTC Core. The documented description is “Call Is Being Forwarded.” In the legacy RTC Client API and SIP-style provisional call signaling, the value reports a nonfailure state that must not be collapsed into plain S_OK.
The application should branch on this result before a generic success path consumes the details.
Where the status is encountered
- RTC call setup and provisional signaling; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
- Roaming capability negotiation;
- Softphone, conferencing, gateway, or proxy call-state UI;
What must be true before accepting it
Verify that the new routing information is accepted by policy and identity or privacy displays are updated correctly. The boundary determines whether the caller continues, waits, falls back, or ends the operation.
Correct handling and recovery
Track the forwarding hop, continue setup, and expose forwarding status without leaking restricted destination information. Detect loops and excessive redirects.
Difference from nearby results
Queued delays handling at an endpoint; forwarding changes the route toward another destination.
Using one generic success branch for this HRESULT and its neighbor can lose output, repeat work, or misreport completion.
Practical scenario
A user calls an office number that forwards to mobile. The client records the forwarding hop and continues the same call dialog.
