Audisho, thank you and it appears it's working. That said partnering with the hosts should mean the setup is smooth as I assumed all of these processes were worked out and the partner host appears to be unaware of the requirement. I did provide our rep the correct, direct number yesterday and again today but it looks like you called the automated line.
This appears to be a far better service than other offerings - I think identifying the form of client at signup would help avoid the issue as apparently all clients hosted in a similar way need this modification.
Thanks
