Our speed dial feature in MyPBX U100 doesn't seem to work even after following instructions from you PDF manual.
Say I want to speed dial a local emergency number 991 which goes through prefix of 0 (any free FXO trunk), what should I do?
Furthermore, in reference to screenshot attached: is "source number" the extension number or the telephone number assigned to an FXO port? I tried both and it doesn't seem to work.
Thank you for your help.
