i am new to Freepbx and i configured around 100 Yealink phones using Endpoint manager and it worked fine. But for some reason i am unable to get the configuration working for Expansion module(EXP40) which is connected to Yealink T46S. i can configure the phone DSS keys using endpoint but the ext keys only can be configured using web portal of the phone but endpoint configuration does not get update.
Anyone come across issues with this config? i assume i am missing a simple step somewhere.
