Well, some staff have moved to a demountable with a switch daisy-chained<br>
from another and it's happening quite a bit now. Looking at the CDR I<br>
can see that one end is just not receiving the packets. The phones are<br>
on the same subnet/VLAN, and the switch ports have no errors. I'm going<br>
to set up a span capture but does anyone have any suggestions on where<br>
to look? CUCM 10.5.2.15900-8, 7975/7965 with SCCP[47]5.9-4-2SR2-2S.<br>
