Sales and support teams that live inside Odoo still jump to a separate phone app to dial, log calls by hand, and reconcile contact lists that drift apart between the two systems. Every un-logged call is a gap in the CRM timeline; every manually keyed number is a chance to misdial; every new contact created in the phone system never makes it back to res.partner. Odoo core has a phone field and the mail.thread chatter, but it has no native computer-telephony (CTI) bridge to a cloud voice provider — no click-to-dial, no inbound screen-pop, no automatic call logging, and no contact reconciliation. That last-mile gap is exactly where teams lose call context and clean data.

ECOSIRE builds a made-to-order integration module that wires your Odoo instance directly to your cloud telephony platform. On the outbound side, we add click-to-dial controls on res.partner, CRM leads, and helpdesk tickets that trigger a call through the provider's telephony API and drop a structured activity/log row into the record's chatter the moment the call connects or ends. On the inbound side, a lightweight CTI listener (webhook receiver plus an OWL/JS overlay) matches the caller's number against res.partner and pops the matching record — or offers one-click contact creation when there's no match. Two-way contact sync runs as a scheduled ir.cron job (and optional real-time webhooks) to keep numbers, names, and ownership aligned between Odoo and the phone system, with a conflict policy you choose during scoping.

Under the hood this is a proper Odoo addon, not a bolt-on script. We define a dedicated model layer (models.Model) for call records, extension mappings, and sync state, with compute/@api.depends fields for derived values like call direction and duration formatting. Provider credentials and endpoints are stored in encrypted system parameters, access is locked down through ir.model.access.csv plus record rules so agents only see their own calls, and every UI surface — the dial widget, the incoming-call overlay, the call-log views, and QWeb call-summary reports — ships as versioned XML/OWL. Outbound requests use the provider's REST API; inbound events arrive on a signed webhook controller; and the whole module speaks Odoo's own XML-RPC/JSON-RPC conventions so it composes cleanly with the rest of your database. We build against your exact Odoo edition and note Community-vs-Enterprise differences (for example where Enterprise VoIP widgets already exist) so we extend rather than collide. Supported on Odoo 17.0, 18.0, and 19.0.

Delivery is build-to-order. After a short scoping call we confirm your telephony provider, call-flow rules, and sync policy, then build on a staging copy of your database, run UAT with your team, and cut over with a rollback plan. Typical delivery is 2-4 weeks from confirmed scope. Pricing starts from $499 (indicative, single-company base scope); additional call-handling extensions, multi-company routing, real-time (vs scheduled) contact sync, and larger historical call-data migration increase the quoted scope. You get a fixed quote after the scoping call — never a surprise invoice.
