Returns the customer's DID (inbound phone) numbers that are activated or suspended; numbers that are still being ordered or have been cancelled are not included. Each number contains its country, name, assigned identity and tags, billing details (monthly fee, next billing date, auto-renewal), whether SMS-to-email is available, and where incoming calls are forwarded to — a SIP URI, a SIP account or a PSTN number, with forward_order showing the configured forwarding type.
