Site has Partner ACS R7.0 with Euro 18D sets. Yesterday the site developed an issue - when trying to call internally from Ext. 13 to Ext. 39, the calls are ringing to Ext. 10 instead of Ext. 39. I had the site contact check Ext. 39 to see if there was a Call Forward button enabled, but contact said there was no button - the only buttons that were labeled were Page All and Voicemail buttons. As all of the site's 18D sets have the same config per the site contact, I did a Copy Settings in case someone accidentally configured and enabled a button, but calls from Ext. 13 to 39 still ring in at Ext. 10. What am I missing?
