Hi there @maly!
Due to network-related parameters, a call will drop at a certain time after 2 hours. Therefore, it's not something that may happen only to you, but to any customer who lasts two hours continuously on a call.
Don't hesitate to let me know if you have any other questions about this topic.
At your service!
Hi. Unfortunately after 2 hours of continuously talk time, the call will drop. This is a network-related settings. In this case you would need to re-dial. Victor21
