MGCP fails for 10 minutes every hour on the hours.

Has anyone heard of this one? This is a network with a pub and a sub, 7225s. All devices are registered to the pub. A 2651 MGCP gateway has 4 FXS ports on it connected to a legacy vmail fujitsu system. The CMs were upgraded from 3.1.3a to 3.2.2c. After the upgrade, the voicemail connected to the gateway would go out for 10 minutes every hour on the hour. The first time it happened, 1.5 years ago, we stopped and resterted the CTI Manager service. This cleared it. Several months later, December of 2002, the vmail on this gateway started going out again. Restarting the CTI Manager service didn't clear it. The fix was to completely reinstall the publisher. It just started again december 2003. The whole thing was reinstalled again, that "fixed" it...again. There were no errors in the log, but apparently, the MGCP signaling goes haywire for only 10 minutes on the hour, everyhour. Nothing else is affected. Also, if you set the Win2000 clock to, say, 8:59, at exaclty 9:00, the vmail will drop again. If you then imediately move the clock to 9:09, it will clear at 9:10. You can repeat this over and over again and it will fail in the same way at the same win2000 time, regardless of what the CMOS clock is. Anyone have any ideas?

Is this something to do with this bug CSCdx48097 or CSCdy25370? seems similar.

Re: MGCP fails for 10 minutes every hour on the hours.

Thanks for the info. It seems very close but they are not running the sst package. At least the "mgcp package-capability sst-package" command is not in the configs. Is there something else to look for to see if sst is on the router? I can't find much information on this SST package or what it does. But both bugs point to it.
