IPO500 embeded VM lost 3 seconds recording

[JM2009]

Dear Experts,

We ran the IPO500 for more than 4 years but recently we found the IPO500 Rel. 11.0 embeded VM lost 3 seconds recording in each voice message for unanswered calls.
The voice mail did not full.
We tried to reboot the IPO 500 but it could not resolve this problem.

Any suggestions is much appreicated.

3 seconds from the start of messages or from the end? What type of external trunks?

With analog lines, the IP Office will sometimes think it needs to remove several seconds of disconnect tone from the end of messages if you have analog lines.

In other scenarios, voicemail starts recording a message when in fact codec negotiation is still going on.

Both can be fixed by looking at your disconnect and codec configs. But meanwhile there are NoUser source numbers for both scenarios that might help:
VM_TRUNCATE_TIME=N where N can be 1 to 7 seconds
VMAIL_WAIT_DURATION=N where N is number of milliseconds.
