Soundpoint IP with Expansion Module

Hi, I use commercial endpoint manager to provision Polycom Soundpoint IP phones, this works for the most part, but I am unable to configure an expansion module added to a Soundpoint IP 560 phone. I configured a BEM-1 module to show Line Keys for all extensions, but it seems that I cannot attach the expansion module to a phone / extension.
I also tried to create a phone directory (that’s the way it worked in the free endpoint manager on a trixbox-system) but while the phone reads it on boot, it does not seem to have any effect. Can anybody tell me how I can accomplish this?

Kind regards,



this is sorted now. In Endpoint Manager the Module can be assigned to the existing phone using Extension Mapping -> Advanced. If you add the BEM-Module here and reboot the phone, it works as expected.
