I have integrated to Avaya Interchage via the Unity Bridge - http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_feature_guide_chapter09186a008045e21d.html
However, I would rather just use Unity and VPIM.
Documentation on Avaya Interchange says it supports VPIM. However, Avaya has told me they require a "Message Networking Box" to integrate via VPIM but that doesn't make sense.
Anyone able to comment on if we can integate Unity to Avaya Interchange via VPIM without needing the Unity Bridge?
Andy, Did a similar integration and Interchange doesnt support VPIM v2 standard. So the client had to upgrade that to Avaya Message networking manager which is the newer product and supercedes Interchange. AMN manager can still integrate with other Avaya Intuity voicemail systems and run VPIM to Unity. You dont need a bridge to to this.
