Hello, We're using sipsorcery v6.0.11 on a Linux machine and .net 6.0

We have faced the following exception:

Unhandled exception. System.AggregateException: One or more errors occurred. (Cannot access a disposed object.
Object name: '[System.Net](http://system.net/).Sockets.Socket'.)

Maybe you will have opportunities to look at this issue.
