Where Else Can Packet Loss Happen?
Occasionally, problems can occur outside of your domain. For instance, if a user complains about a call quality problem, it could be that the other user was on a cell phone, or the problem occurred on the other company's VoIP/UC phone system.
UCaaS Providers: Also susceptible to packet loss are phones, softphones, and Bluetooth headsets. Wireless Bluetooth headsets are not part of IP networks but are networks nonetheless.
