The Tmedia product can configure one of its VoIP Ethernet ports to do Port Mirroring. This is useful when investigating RTP, Codecs or IP Tones issues.
Warning: When configuring a port as a mirror, it is important to connect that Ethernet port directly to a host. Otherwise, it will create problem with to the Ethernet switch
