Why connect the contact center to the company PBX?

Because most complex inquiries are resolved outside the contact center - by engineers, accountants or account managers. When the two are connected, the agent sees who's available and transfers with full context; when they're not, the customer gets a "we'll call you back".

What is shared presence and why does it matter?

One live availability status for the whole organization - agents and employees - in the same system. The contact-center agent sees in real time whether the expert is free, on a call or in a meeting, and transfers only when someone can actually take it.

Does integrating PBX and contact center require replacing both systems?

Not necessarily: on one cloud stack (like PBX.IM and CONTAQT) the connection is built in from day one. Separate systems can be bridged over SIP and APIs - but you lose shared presence and unified logging, so consolidation usually wins.

How long does unifying PBX and contact center take?

On one infrastructure it's configuration, not a project: number porting, org-tree setup and training - a few weeks end to end, with no phone-number changes.

One system for PBX and contact center: the integration guide

Every service manager knows this scene: a customer calls the contact center with a complex technical question. The agent knows exactly who in the company can answer - the engineer on the second floor - but has no way to know if he’s available, and the contact-center system doesn’t even know his extension exists. The result: “I’ll log the ticket, someone will get back to you.” The customer hangs up frustrated, the engineer sees the ticket tomorrow, and a solution that was one call-transfer away is gone.

The problem isn’t the agent or the engineer. The problem is that the contact center (CCaaS) and the company PBX (UCaaS) live in two systems that don’t talk - and customers fall into the gap.

Quick takeaways

The problem: disconnected contact center and PBX = agents blind to the rest of the organization, cold transfers, two vendors and two bills.

The fix: one infrastructure where both share an org tree, presence and logging - so transferring to an expert is one tap with full context.

Why it matters: more inquiries resolved on the first call, fewer callbacks, one CRM record per interaction, and one accountable vendor.

The requirement: UCaaS and CCaaS on one platform or with deep integration - not two islands and a shaky SIP bridge.

What a connected stack looks like: four tests

One org tree, shared presence. The agent opens the company directory and sees everyone - agents, experts, management - with live status: free, on a call, in a meeting. No more “maybe he’s at his desk”.
Transfers that carry context. When a call moves from the contact center to an expert, everything moves with it: who the customer is, what they chose in the IVR, what’s been said - including a screen pop on the expert’s screen. The customer never repeats themselves.
A clean path back. The expert answers and hands the call back for wrap-up? The return transfer joins the same queue and the same record - the whole conversation is one continuous interaction in the CRM, recording and transcript included.
One policy for security, recording and logging. Call recording, permissions, business hours and security policy defined once, applied to everyone - instead of two systems with two policies nobody keeps in sync.

What it’s worth in practice

First-contact resolution jumps. Inquiries that would become “we’ll get back to you” close with one warm transfer. Fewer repeat calls also means less load on the contact center itself.
Organizational knowledge becomes reachable. Experts - the most expensive resource you have - help exactly when needed, without becoming contact-center agents themselves.
One customer experience. The customer doesn’t care whether “the center” or “the office” answered - they feel one organization that knows them for the whole conversation.
Simpler operations and finance. One vendor, one bill, one org tree and one support line - instead of coordinating a PBX vendor, a contact-center vendor and a numbers vendor whenever something breaks at the seam.

Picture a clinic where the front desk books appointments and warm-transfers a medical question to whichever doctor is free, or a logistics company where a service agent connects a customer straight to the dispatcher who’s watching the truck on the map. That’s not a feature - it’s a different way of working.

Three ways to get there

One stack from the ground up (recommended)

When PBX.IM and CONTAQT run on one Reshetcall infrastructure, the connection isn’t an integration project - it’s the default: same org tree, same presence, same numbers, same CRM. Our pricing is built the same way: a PBX seat per employee, contact-center seats only for agents.

Bridging existing systems

Already have a contact center from one vendor and a PBX from another? Bridging is possible - SIP trunks between the systems plus APIs for logging - and it beats total disconnection. Know the limit, though: shared presence and unified logging almost always stay out of reach, so bridging is usually a waypoint on the road to consolidation.

A staged, fully-managed migration

The move doesn’t have to be a big bang: start with the PBX, move one department’s contact center, expand. Our team handles the whole path - scoping, number porting, call-flow design and team training - with everything staying live throughout.

A contact center that can’t see the organization behind it works with one hand tied. Talk to us for a free infrastructure assessment - we’ll map the call flows between your center and your back office, and show you how close the fix is.
