Bug: phone numbers formatted with spaces in them (as is frequently the case when initiating a call from Outlook) seem to be passed along to the server with the spaces present, which causes the call to fail. I assume that the 3CX server dislikes spaces in the called number field. Either the VOIP softphone needs to strip space characters, or the server needs to be changed to ignore space characters? It would be a pain to go through thousands of phone numbers in our Outlook public folders to edit out all spaces which are preset in the phone numbers. People leave the spaces in the phone numbers in order to ease the process of dialing manually from a number displayed on sceen.
