fix(voice-call): pin plivo callback origins (#58238)

CHANGELOG.md

@@ -78,6 +78,7 @@ Docs: https://docs.openclaw.ai
 - Memory/QMD: keep `memory_search` session-hit paths roundtrip-safe when exported session markdown lives under the workspace `qmd/` directory, so `memory_get` can read the exact returned path instead of failing on the generic `qmd/sessions/...` alias. (#43519) Thanks @holgergruenhagen and @vincentkoc.
 - Memory/QMD: treat null-byte collection corruption the same when QMD surfaces it as `ENOENT`, so managed-collection repair still rebuilds and retries instead of leaving QMD stuck on a broken path. Thanks @vincentkoc.
 - Memory/QMD: stop rewriting Han/CJK BM25 queries before `qmd search`, so OpenClaw search semantics match direct QMD results for mixed and spaced Chinese queries. Thanks @vincentkoc.
+- Voice call/Plivo: pin stored callback bases to the configured public webhook URL so later call-control redirects stay on the intended origin even if webhook transport metadata differs. Thanks @zsxsoft and @vincentkoc.
 - Agents/memory flush: keep daily memory flush files append-only during embedded attempts so compaction writes do not overwrite earlier notes. (#53725) Thanks @HPluseven.
 - Web UI/markdown: stop bare auto-links from swallowing adjacent CJK text while preserving valid mixed-script path and query characters in rendered links. (#48410) Thanks @jnuyao.
 - BlueBubbles/iMessage: coalesce URL-only inbound messages with their link-preview balloon again so sharing a bare link no longer drops the URL from agent context. Thanks @vincentkoc.
