No IPSLA MOS score in VOIP monitoring? NFA 9.8
Hi,
We recently configured some VOIP monitors in version 9.8 all the jitter and rtt seems to report ok but the MOS score always shows 0.0. It doesn't seem to be retrieving the value from the router. even thought the router is correctly calculating a MOS value.
