Hello,
We are frequently experiencing high peer latency (reaching above 5 seconds and as high as 20 seconds) between our Media Gateway and Opensips (as well as Genesys Servers). See attached screenshot. Call flow is from Genesys Servers to Opensips Server and to Media Gateway.
Restart of ASTERISK service does not resolve the issue. There has been many changes done on our Network connection (voice traffic has been removed from Firewall, voice traffic has been moved to a connection where there is no other traffic but voice) but to no avail.
At the moment our Network Team is seeing UDP errors in Grafana and they are suspecting that this is causing the problem.
- NoPorts - UDP Datagrams received on a port with no listener
- InErrors - UDP Datagrams that could not be delivered to an application
I currently don’t know if the UDP errors are caused by the high peer latency or if it causing the high peer latency.
I would appreciate any help and recommendations you can provide to investigate on this issue.
Thanks in advance.
