For some reason, the cloud mail invite is adding an extra character in the dial string that is causing the call to fail.
The forward slash added at the end of the dial stream is causing the issue (should not be there.) Once deleted, the call goes through without any issues.
I'm sure this will be resolved fairly quickly but I wanted to let Lifesize Community know if the issue and how to get the call to go through.
Best regards, Ricardo Colunga.
