Geo‑Routing Capabilities Before Finalizing RC Subscription

My company is trying to find a RingCentral third‑party application that can geo‑route inbound calls by ZIP code. I’ve been trying for a months to get this answered through RC Sales, and last week I was finally pointed to the Developers site.

For context: I run nationwide marketing campaigns that rely on shared-use call flows. TV or radio spots promote a single phone number. When a viewer or listener calls, they’re prompted to enter their 5‑digit ZIP code, and the call is then transferred to a participating business in that specific area. Think of models like 1‑800‑Flowers, 888‑92‑NoPain (chiropractors). 

This ZIP‑based routing is essential to how our campaigns operate. I need to know whether RingCentral can support this—either natively or through a compatible third‑party solution—before I proceed with onboarding.

Thank you in advance for helping me get a definitive answer.
