Does Avaya CM/AES support queue metrics that I can display in our app during a transfer?

For example, if an agent is transferring to a queue, we want to pull the average or current wait time so we can display it

DMCC or TSAPI

Unfortunately not directly,

See this FAQ

While the FAQ is JTAPI oriented you can implement a similar methodology with TSAPI and DMCC call control.

It may be possible to get/calculate useful values using the VuStats feature. There is more information on this at:

For vustats do we require advanced tsapi dmcc license or will basic license work.

a 'normal' DMCC license is needed to access vu-stats. You do not need a TSAPI Advanced user license. You are using button & display station functionality through DMCC. You will also need an IP Station and basic station license on CM - probably per split you want to monitor, although you may be able to have vu-stats "menu's" that cover more than one skill on a single station, but there is an upper limit to where you can take that model. there may be other ways to stretch how you use a station to cover more than one skill (multiple vu-stats buttons? IDK).
