Everything you want to know about DRIN PRO

DRIN PRO is a fully cloud-based UCaaS (Unified Communication as a Service) platform built on Yeastar P-Series Cloud Edition. Unlike a traditional on-premise PBX, it requires no proprietary hardware: PBX, video conferencing, chat and call centre services are delivered from ISO 27001-certified Italian datacenters, with activation in under 24 hours and instant scalability.

Standard activation takes 4-8 working hours from order confirmation. For Enterprise plans or custom configurations (geographic number porting, CRM integrations, multi-site) the time may extend to 24-48 hours. The Skillworks team supports the customer through every onboarding phase.

For each concurrent call, a bandwidth of 100 kbps with G.729 codec or 64 kbps with G.711 is recommended. The connection must have jitter below 30 ms and packet loss under 0.5%. A dedicated or business fiber line with QoS enabled on SIP/RTP traffic is recommended.

Yes, DRIN PRO supports porting of geographic numbers (02, 06, 011...), mobile and national numbers to the cloud platform. The porting process takes an average of 15-30 working days and is managed entirely by the Skillworks team, keeping the old number active until completion.

Yes. The platform allows managing multiple sites with a single distributed PBX: each site can have its own extension range, opening hours, IVR and separate queues, with free internal calls between sites and a single centralised administration.

Yes. You can customise the first part of the FQDN (the PBX name), while the domain remains fixed on [myname].dc1.yeastarcloud.it or [myname].dc2.yeastarcloud.it depending on the assigned datacenter. For example, a company "Smith Ltd" can obtain smithltd.dc1.yeastarcloud.it. The PBX name is chosen during onboarding and can be changed later by request to support.

The admin panel is accessible from any modern browser: Chrome, Edge, Firefox, Safari (last 2 versions). Linkus clients are available for Windows, macOS, Linux, iOS and Android. No additional plugins are required.

Yes, a 30-day free trial is available with all features enabled. At the end of the trial you can convert to a subscription while keeping the configuration and data. Request a demo from the form on the Contact page.

Backup is automatic and daily, with 30-day retention. Data is replicated in real time to the secondary DC2 Bologna datacenter for Disaster Recovery, with RPO of 1 hour and RTO of 4 hours as specified in the SLA.

Yes, DRIN PRO is fully GDPR-compliant. Data is hosted in Italian datacenters owned by Skillworks S.r.l., the Data Processing Agreement is available on the GDPR & DPA page, and no data is transferred outside the EU (except for third-party AI services with adequate safeguards).

DRIN PRO supports internal and external VoIP calls, outbound calls to PSTN (national/international landlines and mobiles), inbound calls with geographic DIDs, audio and video conference calls. Supported codecs include G.711, G.722, G.729, Opus and standard SIP 2.0 protocol.

Yes. DRIN PRO supports toll-free (800 equivalent), urban (02, 06, 011...), national and international numbers in over 60 countries. Numbers can be activated directly from the admin console or requested from the Skillworks team.

Yes. Ring Groups (simultaneous ringing to multiple extensions), Hunt Groups (sequential ringing with custom strategies) and Paging Groups (one-way announcement to multiple extensions) are available. Each group supports timeout, fallback to voicemail or IVR, and activity hours.

Yes. All calls between DRIN PRO extensions — even between different sites of the same corporate group — are free and unlimited, regardless of the subscribed plan. They do not consume minutes included in the plan and do not generate additional costs. Internal traffic remains end-to-end encrypted within the Italian cloud infrastructure.

Each extension has a personal voicemail with email notification (audio attachment + AI transcription if active), web access, custom greeting, and PIN protection. Voicemail-to-email forwarding rules can be configured according to user preferences, with custom notifications for hours and days.

Yes. DRIN PRO integrates a spam blocking system with manual blacklist, IP auto-defense with Fail2Ban, country access restriction (blocking entire countries), and behaviour-based spam pattern detection. Administrators receive monthly reports on blocked calls.

Linkus is available as a mobile app for iOS and Android, desktop client for Windows, macOS and Linux, and web client accessible from the browser. All clients support calls, chat, presence, file sharing and video calls. See Linkus Clients.

DRIN PRO supports major IP phones through standard SIP auto-provisioning: Yeastar T-Series, Fanvil, Grandstream, Sangoma, Snom, Yealink and Cisco SPA. The full list is available on Compatible Phones, with pre-configured provisioning templates.

Yes. Linkus supports 1-to-1 video calls up to 1080p and multi-party video conferences up to 100 participants (Enterprise+ plans). Screen sharing, integrated text chat, meeting recording and Google/Microsoft calendar integration are supported.

An active internet connection is required for VoIP calls. However, Linkus Mobile can receive push notifications even when the app is closed, ensuring you never miss important calls. Chat supports message queuing and automatic sending when the connection is restored.

Yes. Linkus Mobile and Desktop support Bluetooth and USB headsets (Jabra, Plantronics, Sennheiser, Logitech). On desktop you can configure the preferred audio device for calls and hold music separately.

Check: 1) internet connection (jitter <30ms, packet loss <0.5%), 2) codec in use (prefer G.722 or Opus), 3) router QoS enabled for SIP/RTP traffic, 4) correct audio device. If the issue persists, open a ticket on Support with a Linkus diagnostic test attached.

Yes, the same extension can be registered on multiple devices (e.g. desktop + mobile + web) simultaneously. Incoming calls will ring on all, outgoing calls can be initiated from any device, and presence updates in real time on all clients.

Yes. DRIN PRO supports integration with certified Fanvil video intercoms (e.g. i10/i20/i30 series): calls from the intercom are received on Linkus clients (desktop, mobile, web) with two-way audio and video preview of the visitor before opening the door. Door release can be triggered directly from the client via DTMF or API, with the ability to take a photo of the guest and log the event in the access log.

AI Receptionist is an LLM-based virtual assistant that answers incoming calls in natural language, handles bookings, provides company information and routes calls to the correct department. It supports IT/EN/ES + other languages and operates 24/7 with no wait. See AI Receptionist.

Recorded calls are sent to an AI engine (OpenAI Whisper, Google, or ElevenLabs) that generates real-time text transcription with >95% accuracy. Transcripts are searchable, exportable and can be used for analytics and automatic summary. See AI Transcription.

DRIN PRO supports multiple selectable AI models: OpenAI GPT-4 (for conversation agents), Google Gemini (for multilingual transcription), ElevenLabs (for natural TTS), Amazon Transcribe (for compliance). The model choice depends on the use case and subscribed plan.

Only for explicitly activated AI services. Transcriptions are sent to AI providers (OpenAI, Google, ElevenLabs, Amazon) exclusively for the requested processing, with GDPR safeguards (Standard Contractual Clauses, no training use). Disabling AI services means no data leaves the Italian datacenter.

All DRIN PRO AI services (Receptionist, Transcription, Voice Synthesis) are optional and individually activatable. The administrator can disable them at any time from the administrative console, "AI Services" section. Once disabled, no data leaves the Italian datacenter and calls are handled exclusively by the PBX without AI processing. Disabling is immediate and requires no system restart.
