Ecommerce teams that run call centers alongside WhatsApp have two completely disconnected operations. Phone calls live in the PBX — orders, messages, and CRM data live everywhere else. Nexus integrates with Issabel PBX to bring click-to-call, CDR sync, and call recordings directly into customer profiles, so agents always have the full picture regardless of which channel a customer uses next.
Ecommerce businesses often run phone-based and WhatsApp-based customer service in parallel — but these channels are never actually unified. A customer calls to complain about a missing order on Monday and messages on WhatsApp on Thursday. The agent handling the WhatsApp message has no idea the call happened. The customer has to repeat their entire story. The operation looks unprofessional and the agent loses time reconstructing context that already exists — just in a system they can't see.
Every call that happens through the PBX is logged only in the PBX. There's no record of call outcomes, what was discussed, or which agent handled it in the customer's CRM profile. The operational history that matters most — what was promised, what was resolved, what was escalated — lives in a silo that nobody else can access.
Call notes are either not taken, written in a separate spreadsheet, or stored as disconnected recordings that no one revisits. When a dispute arises about a commitment an agent made on a call, there's no easy way to surface the recording alongside the relevant order or message thread. Context is permanently lost the moment the call ends.
A customer who called twice last week to resolve a return sends a follow-up message on WhatsApp. The agent opens Nexus and sees no context — no record of the calls, no notes, no outcome. They either message the customer asking them to repeat themselves, or make a decision without the information they need. Either way, the customer experience suffers.
Nexus integrates with Issabel PBX to create a direct link between your phone operations and your CRM. Every call is automatically logged against the customer's Nexus profile. Click-to-call lets agents dial from any contact record. Call recordings sync into the customer's interaction timeline. When a customer switches from phone to WhatsApp, the agent picks up a complete conversation history — calls, messages, orders, and returns — in one view.
When a call ends — whether inbound or outbound — Nexus automatically pulls the CDR from Issabel and logs it against the customer's profile. Call time, duration, agent extension, and any notes added post-call are stored in the customer's interaction timeline alongside WhatsApp messages and order events. The PBX and CRM stop being separate systems from that point forward.
Agents can initiate a call to any customer directly from their Nexus profile with a single click. The call routes through Issabel — no manual dialing, no copy-pasting numbers into a separate softphone. The moment the call ends, it's logged automatically. Dialing errors are eliminated and every call is captured without the agent needing to do anything after they hang up.
Recordings captured by Issabel are synced into Nexus and attached to the customer's interaction timeline. A manager reviewing an escalation can play back the call that started it, read the WhatsApp thread that followed, and see the order status — all in one customer profile. No separate PBX dashboard, no asking agents what happened on a call from three days ago.
Stop running your call center and your messaging operation as separate systems. Nexus integrates with Issabel PBX so every call is logged, every recording is linked, and every agent has the full customer history regardless of which channel they pick up. Start free, no card required.
