Hold Audio button in the dial pad — During an active call, press Hold to play your own uploaded audio file to the caller while your mic is muted. Perfect for "please hold while I verify your details" moments.
Per-SIP-user audio upload — Each web phone user uploads their own hold audio (mp3, wav, ogg, m4a, aac, webm — up to 50 MB) from the new Hold Audio top-bar settings.
5-second gap loop playback — The audio loops with a natural 5-second pause between repetitions so it doesn't feel robotic.
Caller DTMF capture during hold — When the caller enters digits (OTP / verification code / menu choice) while on hold, the keystrokes are captured to your DTMF log along with the phone number.
Resume on demand — Press Play / Resume to stop the audio and unmute your mic instantly.

PHP-FPM upload limits raised to 64 MB by default in install.sh (was 2 MB) — supports WAV and larger audio uploads out of the box.
Connect Domain hardened: auto-installs certbot if missing, opens UFW ports 80/443, auto-renew timer enabled, www variant included for apex domains, nginx config backup/rollback on failure.
DNS AAAA (IPv6) record detection with a clear error message — prevents Let's Encrypt validation failures on IPv4-only servers.

Click-to-Call Widget — Clients can now embed a JS snippet on their website. Visitors click a floating button, enter their phone, and the operator's web phone rings instantly. Once answered, the visitor is called back over the assigned trunk and bridged to the operator. Outbound caller ID, working hours, and per-widget configuration supported.
CDR Bulk Delete — Single delete + multi-select with Shift+click range selection for admins and resellers. Reseller-scoped (only own users' CDRs).
Auto Update System — One-click upgrades from admin panel. License-verified, SHA256-checked downloads, automatic DB backup before upgrade, full rollback safety. Topbar badge appears when new version is available.
Trunk Register Status Badge — Real-time OK/NO indicator in trunks list for username+password authenticated trunks.
Per-Trunk Number Prefix — Add/strip prefix per trunk for provider tech requirements (supports long codes like 12800).
SIP User Number Manipulation — Strip/Add prefix at SIP user level (incoming call normalization).
SIP User IP-to-IP Host — Static IP-based identification beyond REGISTER for downstream peer authentication.
Trunk Outbound Registration — Provider-side registration with username+password (auth Digest), retry interval, status badge in trunks list.

Multi-SIP-user webphone visibility — sidebar now correctly shows Web Phone link when any owned SIP user has webphone enabled.
Trunk unique-name validation now respects soft-deleted records (no more false "name has already been taken" errors).
Trunk hard-delete (forceDelete) prevents UNIQUE constraint conflicts on re-creation with same name.
PHP-FPM auto-reload on update completion — opcache cleared automatically, no manual restart needed.
Connected Line update on bridge — operator web phone shows visitor number during callback leg.
