I have an unusual problem. When I'm connected wirelessly to my ISP (CarryTel) I am unable to make outbound calls via teams to contacts within my organization. Two things happen when I make the outbound calls 1. The people hear my voice and see my video but I can't see them or hear them, and then the call drops. 2. The call connects, it's a blank screen and then drops automatically.

 

I can receive calls, both voice and video from people within my organization. 

 

When I tether to my phone, I am able to make outbound calls to people within my organization. When I connect to another wireless network (outside of my home) I can make outbound calls.

 

Obviously, something is wrong with my ISP/Wireless connection. But what? Has anyone noticed this issue before?

Hello @zkleiman  I'm going to ask @Chris Webb to help here

@zkleiman I'd try using web client and see if issue persists. Also another device if possible like your phone app on your wifi. Since your initiating the call, either your firewall or ISP may be blocking or doing something with the data that Teams uses. When you take an inbound call it's probably on random ports so it doesn't effect it the same. 

@Chris Webb Thanks for the quick response. The web client worked for outbound calls. It felt good to finally do a successful outbound call!

 

 What do you propose as the next step now that we've somewhat isolated the issue?
