CRM With Phone Ticketing Integration

I want to put a proper customer-support CRM in place and tie it directly to my Grandstream UCM6302 PBX. The core requirement is a ticketing system: every time a call comes in, I need the caller’s details to pop up, a new or existing ticket to open automatically, and the call log (plus recording, if possible) to attach to that ticket.

If you know a platform—open-source or commercial—that can do this reliably, I’m open to your recommendation as long as the focus stays on customer support rather than sales or marketing automation. Zoho, SuiteCRM, Odoo, Freshdesk, FreePBX integrations, or anything similar is fine as long as you can prove the UCM6302 will talk to it (AMI, REST API, webhooks, etc.).

Deliverables
• Working CRM instance with ticketing enabled
• Tested integration to the UCM6302 for incoming & outgoing calls (screen-pop, ticket auto-creation, call log/recording attachment)
• Basic agent workflow documented (open, update, close tickets)
• Short hand-off session so my team can maintain it

Bring your experience with VoIP/CRM bridges, be ready to configure extensions, and feel free to suggest any lightweight middleware if a direct plug-in doesn’t exist.
