I have an Trixbox/Asterisk PBX. I am trying to configure endpoint manager support for the Grandstream HT502. I have directions on how to set this up and have already done so. apparently during installation something did not go correct and I need an experienced Asterisk/Trixbox/PHP Guru to help resolve the issue. I need this work completed ASAP. If you are highly skilled with trixbox please contact me.
