We are using Endpoint Manager as have a problem with Aastra Expansion Modules.
We have set up a template for both a 6757i using a 675i expansion module and also a 6867i with a M685.
Neither expansion modules get programmed and just appear blank. The handsets are working fine however.
we know the expansion modules are working because if you log into the phone via the web manager you can configure them manually.
Looking at the support documentation the 675i expansion module is listed as being supported but the M685 isn’t yet listed. ( http://wiki.freepbx.org/display/FCM/EPM-Supported+Devices )
Is this a known issue, its a pretty basic setup so i can’t imagine we have done anything wrong.
