Thank you for the insight and it does make a little sense seeing just after I had posted my question the router neede to be rebooted and then when it first came on I had wifi calling but then soon after I did not. Having said this I am very, very confused though. The reason I am confused is that others in the office are able to get their T-Mobile phones and wifi calling to connect with the router. Any suggestions as to trouble shooting why my wont seeing the other 2 will? Is it a game of he who gets here first and activates it first gets to the router to respond to them and work?
Hrm...I would see if a firmware update is available for your router. Having multiple devices might be doing something awkward to the router's routing tables.
Any chance you can verify it consistantly works on another wifi hotspot/router? If it works ok on those systems, it's likely your specific router firmware (or related proxy systems @ businesses) that cause issues.
