Twilio Two-Way SMS CRM Integration

I need my existing Twilio number configured for true two-way SMS chat support and fully wired into my CRM. Outbound texts must send directly from the Twilio number, and any reply must flow straight back into the same customer record so agents can pick up the conversation without leaving the system...
