Hello all! I buyed the SBS Version of 3CX! Sometimes all incoming calls works fine and sometimes nothing works! Im from Austria and my Service Provider (UPC Austria) told me that this Software should work without Problems! What can i do that this PBX works permanently? :lol: First Error: Calling Extension directly from outside! http://www.3cx.com/support/source-identification-err-2.html I follow this Guide but it doesnt help! If i restart, it works for an Hour than it stops working! Second Problem is the Fax: I got a normlay Faxdevice connected on a Grandstream Handytone 286! For Example Extension Number 15 (i have to call directly from outside) Guys im not a PRO on this Software i need your help! Thanks for any Answers!
