Phone calls drop after 30 minutes

[madami16]

Phone system has been working great for our business. However we are encountering a small bug where our phones drop calls as soon as they hit the 30 minute threshold. Is there a fix for this?

Thanks in advance.

Have you checked the Activity Log to see which end drops the call? Does this happen on internal and external calls? Do you have more that one outbound route? If so, does it happen on multiple routes? Did this just start?

Hi @madami16

As above please check who drops the call. It's important in order to understand why.
