When integrating Avaya IX™ Messaging with a third-party PBX, especially in a multi-PBX or multi-node environment, the system supports Message Waiting Indicator (MWI) with Session Initiation Protocol (SIP) and Computer Telephony Integration (CTI). This allows for a flexible and scalable messaging system that can work with various PBX configurations. Additionally, while different trunk types can be used for integration, it is recommended to use SIP trunks for all PBXs/nodes to ensure a more streamlined and consistent integration process.
