about the VOIP bandwidth

Hi, all: I'm using wireshark to capture VOIP streams, the Codec used in the VOIP session is G711, which uses bandwidth of 64kbps. When I follow the following steps to analyse the VOIP streams: Telephony->RTP->show all streams->Analyze, I found that the IP BW (bandwidth) column shows that the bandwidth is about 81.6 kbps. I also used a traffic monitoring program to monitor the traffic, which shows the bandwidth used is about 64kbps (conformant to G711 bit rate ). So, I wonder whether wireshark is accurate in measuring the bandwidth? or even other metrics such as jitter,etc.. Thank you!
