Telephony Integration: Bandwidth

Enable native integration with Bandwidth, allowing agencies to connect their own Bandwidth accounts and provision phone numbers directly to AI agents.

The integration should support automated number assignment, routing, and lifecycle management from the agency's Bandwidth account. Additionally, agencies should be able to leverage their existing A2P 10DLC registrations and messaging compliance setup within Bandwidth for SMS-enabled AI agents.

This feature provides greater flexibility, simplifies telephony management, and allows agencies to maintain full control over their voice and messaging infrastructure.
