Genesys t-lib SDK specialists...help

[Genecist]

I have a question regarding using the t-lib sdk to monitor for an agent login on a hard phone.

I know that it's possible to regester a DN of type AddressTypeDN and receive an EventAgentLogin event, and then get the id of the agent that logged in to a hard phone represented by the registered DN.

But is the 'flip' side possible?

That is, is it possible to register a DN of type AddressTypeAgentID and get a EventAgentLogin event for that agent DN in order to retrieve the hard phone extension that the agent logged in too?

I've done numerous code experiments and I've never been able to receive EventAgentLogin on a DN of type AddressTypeAgentID...which seems pretty silly.

Any help is appreciated.
