Source notes citing this source

• Avaya's documented coexistence pattern preserves CS 1000 extension dialling by mirrored routing (vacant number routing or digit manipulation on CS 1000 and SIP routes back on Aura) rather than by an automated import of the CS 1000 dial plan. inferred in context
• During phased migration Avaya Aura must have SIP routes back to CS 1000 for the extension ranges that remain on CS 1000. in context
• Avaya's phased migration divides existing CS 1000 endpoints into groups migrated in batches to reduce downtime and the risk of a major fault. in context
• Each endpoint migrated through Device Adapter consumes the same Aura capacity allocation as any other Aura SIP endpoint, so Aura must be sized for the added endpoints. in context
• Calls from CS 1000 to already-migrated endpoints can be routed with vacant number routing or with specific digit manipulation tables on CS 1000. in context
• Group features such as Multiple Appearance Directory Numbers (MADN) break if their members are split across migration phases, and members spread across several MGCs require migrating those MGCs together. in context
• During phased migration, migrated users can use Aura's centralized SIP trunks for PSTN access or keep using CS 1000 TDM DID trunks, with vacant number routing on CS 1000 sending calls on to Aura. in context
