What it is
Corporate phone service over IP. An internal PBX with extensions, forwarding, voicemail, IVR. External lines via a SIP provider or traditional analogue / PRI trunks.
What’s included
- PBX: Asterisk, FreePBX, 3CX — chosen by user count and feature mix. From 5 to 500+ extensions.
- External numbers: multi-channel toll-free and local numbers, porting existing numbers between providers.
- Features:
- Extensions and ring groups
- IVR with weekday / weekend / night routing
- Call recording with secure storage
- Voicemail-to-email
- Call queues for sales and support
- Remote staff: mobile app or laptop softphone — internal extension works from anywhere.
- Integrations: customer card pops up in the CRM on incoming call, missed-call notifications, automatic task creation in 1C / amoCRM / Bitrix24.
- Conferencing and video: built into the PBX or integrated with Zoom / Jitsi.
When you need this
- Switching providers or PBX — migration without service interruption.
- Expanding: new office, remote staff, need to unify telephony.
- You want to integrate calls with the CRM for the sales team.
- An old analogue PBX is end-of-life, support costs are rising, time to replace.
Approach
Not locked into a single provider or PBX. If today’s best combination is Asterisk plus a domestic SIP provider, we deploy that. If conditions change tomorrow, we migrate without losing numbers or call history.
