@@ -76,6 +76,7 @@ Docs: https://docs.openclaw.ai
 - Providers/OpenAI-compatible: forward `prompt_cache_key` on Completions requests only for providers that opt in with `compat.supportsPromptCacheKey`, keeping default proxy payloads unchanged. Fixes #69272.
 - Providers/ElevenLabs: omit the MP3-only `Accept` header for PCM telephony synthesis, so Voice Call requests for `pcm_22050` no longer receive MP3 audio. Fixes #67340. Thanks @marcchabot.
 - Plugins/Voice Call: reap stale pre-answer calls by default, honor configured TTS timeouts for Twilio media-stream playback, and fail empty telephony audio instead of completing as silence. Fixes #42071; supersedes #60957. Thanks @Ryce and @sliekens.
+- Plugins/Voice Call: terminate expired restored call sessions with the provider and restart restored max-duration timers with only the remaining duration, preventing stale outbound retry loops after Gateway restarts. Fixes #48739. Thanks @mira-solari.
 - Skills: honor legacy `metadata.clawdbot` requirements and installer hints when `metadata.openclaw` is absent, so older skills no longer appear ready when required binaries are missing. Fixes #71323. Thanks @chen-zhang-cs-code.
 - Browser/config: expand `~` in `browser.executablePath` before Chromium launch, so home-relative custom browser paths no longer fail with `ENOENT`. Fixes #67264. Thanks @Quratulain-bilal.
 - Telegram/streaming: hide tool-progress status updates by default while keeping explicit `streaming.preview.toolProgress` opt-in support for edited preview messages. Fixes #71320. Thanks @neeravmakwana.
