MDD Sim Gateway v1.5.0

升级提示： 首次升级至 v1.5.x 时，Engine 镜像会在“正在重建并重启服务…”阶段下载；受网络速度影响，此阶段可能持续较长时间，请勿断电或重复发起升级。

• 新增语音信箱，未接听的来电可以在本机录音并直接从通话记录播放。

Upgrade notice: On the first upgrade to v1.5.x, the Engine image is downloaded during “Rebuilding and restarting services…”; depending on network speed, this stage may take an extended time, so do not power off the gateway or start another update.

New features

• Added a Balance and Number Keeping page for viewing line status, balance, renewal requirements, and expiry dates in one place.
• Added scheduled number keeping, using a chargeable SMS or renewal-balance monitoring according to the line type.
• Added voicemail, allowing unanswered calls to be recorded locally and played directly from the call history.
• Added missed-call notifications, with voicemail notifications replacing the missed-call alert to avoid duplicate messages for the same call.
• Added release notifications through Webhook, Telegram, and PushPlus.
• Added optional automatic updates controlled by a separate policy that specifies the approved version and earliest rollout time.
• Added a “Keep me signed in for 30 days” option, with sessions surviving service restarts and software updates.
• Added a GitHub Release upgrade channel for Engine images with direct/proxy fallback, download progress, integrity verification, and rollback on failure.

Bug fixes

• Fixed Issue #10: multiple identical USB readers without serial numbers could incorrectly assign different SIM cards to the same Instance.
• Fixed Issue #12: Docker self-updates could recreate the control container without the sing-box, xray, and host mappings required for network-exit tests.
• Fixed sign-in sessions being lost after a control-service restart or software update, which signed every browser out.
• Fixed affected WiFi Calling lines remaining stopped instead of registering again after an Engine update.
• Fixed reload potentially continuing to use the previous Engine image after a manual rebuild.
• Fixed locally cancelled carrier service codes sometimes being reported as rejected by the carrier.
• Fixed the softphone not explaining that WebRTC was disabled by the browser.
• Fixed several device states appearing in English or as raw status codes.
• Fixed notifications not identifying which gateway sent the message.
• Fixed ARM64 Engine release builds potentially hanging on slow upstream downloads by adding timeouts, low-speed detection, retries, and resume support.
