For a variety of reasons, a component in a system may be operational to enable telephone calls utilizing a particular dialing format but be inoperable for calls utilizing a different format. Telephone number formats were initially numeric. The number of digits and format of the digits was often determined based on a country-specific dialing plan. Many countries have moved to more digits or alphanumeric formats (e.g., URIs). By capturing these enhanced addresses and generating an associated unique identifier, internal networks may utilize legacy numbering systems internally and, once the call reaches an edge device, route them based upon the enhanced address."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Call routing between enhanced and legacy systems","description":"Components of a telephone system often do not evolve in lock-step with other system improvements.
