We have a system in place that monitor network traffic. We have been told that there has been an increase in traffic from ports 1695,1148,1687,and 1685 on the CallManager. Was wondering if anybody knew what kind of traffic these port send?

Hi, none of those ports are used by CUCM:

I've looked up the ports you mention above and according to IANA they are as follows:
rrilwm Port 1695 TCP rrilwm
rrilwm Port 1695 UDP rrilwm
elfiq-repl Port 1148 TCP Elfiq Replication Service
elfiq-repl Port 1148 UDP Elfiq Replication Service
nsjtp-ctrl Port 1687 TCP nsjtp-ctrl
nsjtp-ctrl Port 1687 UDP nsjtp-ctrl
n2nremote Port 1685 TCP n2nremote
n2nremote Port 1685 UDP n2nremote
