Thank you for the reply, Nick. It turns out that the reason the conference emails were not being sent is because Exchange 2013 is preventing the email I setup for 3CX from relaying. As a workaround until I figure that out, I setup a gmail address for the 3CX and that is working as it should. Any suggestions on getting that through? I tried setting up a receive connector using the 3CX server's IP address, but it is still not relaying.
Now that I can get the emails to go through, the new issue I'm facing is getting the full dial number available as a link. With the old phone system, I set it up so that conference rooms were listed with the full external number, a comma, the conference extension, another comma, and finally the conference ID number (xxxxxxxxx,xxx,xxx). When all of these numbers and commas are connected, a mobile phone user could simply click the link from their device and the phone would automatically dial each number after a pause. I was able to get the external number and conference extension setup by defining it in the PBX conference DID settings, but how can I get it to at least display in the message? If I put %%EXTERNALNUMBER%%, %%CONFERENCEID%%, the phone (and Outlook) does not see the conference ID as part of the number due to the space, but if I put them together, 3CX complains that that parameter does not exist. Any suggestions on how to combine the parameters without the space? The absolute best option would be if I could get that setup as the Conference DID number when a conference is scheduled as that is the number displayed at the top of the calendar invitation. Thanks again!
