Which Avaya Integration?

We have an Avaya G3R PBX that we want to integrate with Unity. Unity 4.x appears to have two Avaya integrations that might fit the G3R:

Avaya Definity G3 DTMF

Avaya Definity Gx/PBXLink

I know next to nothing about Avaya's PBX's; would a G3R be a "G3 DTMF" integration or do I need a PBXLink box?

Re: Which Avaya Integration?

Either integration should work for you. The main difference is cost will be...

- in-band DTMF integration requires Mode Code feature on the Definity

- serial SMDI integration requires one or more PBXLink devices

Feature-wise, they are similar however with the PBXLink you can get Forward to Busy Greeting. The in-band DTMF cannot provide this.

Support-wise, in-band DTMF may be a bit less work because no 3rd party hardware (PBXLinks) is required.

Re: Which Avaya Integration?

Thanks. If I recall, the "Forward to Busy Greeting" is a unique greeting that Unity can play when the destination Unity subscriber is on the phone as opposed to a standard greeting for no answer. The caller would get the standard greeting instead. Is that correct?

Re: Which Avaya Integration?

Yes, that is correct. Basically this feature requires that the phone system provide us with a Forward Reason Code. Without this we just route all forwarded calls to the standard greeting.
