Anyone setup AT&T SMS Integration? All I know to do is put in the cell number and then append @txt.att.net to the end of it. Not sure how to do this in the SysAid text message integration. I select Cutom Provider and it's asking me for the Username, Password, Sender ID, Gateway ID...etc. Where can I find this info? I can't seem to find it on any of the AT&T websites.
