[cisco-voip] CXN 9.1.2.14900-661 Garbled Messages

[Jason Aarons (AM)]

The ntp server was a 6509 with “ntp master 10” setup.  However the delay/offset/jitter are both high to that 6509.  I changed it to ntp master 2 and will monitor RTMT for syslog alerts.

Jason,

Fix NTP then restart conversation manager primary first, the HA.

Find a IOS router for now, if you can, and host a local ntp master at Strata 2 for the primary.

G711 recording format, SIP integrated with CUCM 9.1.2.14900-14

Any known bugs?

I did notice via RTMT syslog alert that NTP is Stratum 10 and am working to have them open a firewall port for NTP for public stratum2 ntp server, or buy a GPS NTP box etc.
