[c-nsp] Wireshark RTP Stream - Packet Lost in Neg value over the WAN

[Farooq Razzaque]

Hi All
 
Attached is the screen shot of wireshark (capturing RTP stream). In Lost column it is showing -300% , -299.7% packet lost. 
 

Does anybody have any idea that are these packet loss is normal/abnormal over the WAN as there packet lost are in -neg.
 
IP phones ( 172.20.24.x) are located in one bracnh and Recording machine (172.20.19.17) is located in other branch. These branches are connected via MPLS link
 
For recording the calls, SPANing is happing over the WAN via L2TPV3.
 
There is no issue with calls recording and quality.
