I have a 28port KeyVoice Interchange VM system running v 10.4 with 3 Dialogic D/41H and a D/160SC-LS on a Win2k platform. The PBX is a Harris 20/20 LH (now Techtronics) We have been suffering an intermittent major issue and a minor issue since we upgraded from version 9 two years ago. We are running Diskeeper to autodefrag the drives on the system. The message store drive is defragged every hour. The rest of the system is defragged every twelve hours.
The minor issue relates to the VM system coming online after a reboot. We have found that it can take up to 15 minutes after a sucessful reboot for the VM to come online. There are no associated error messages or event logging for this. We have found if we stop and start the Dialogic service a couple of times we can get the amount of time down to 8 minutes. This did not occur under version 9.
The major issue involves a hard cutoff from the voice mail system when leaving a message. This is an intermittant issue. We have seen the issue for both internal and external callers.
We have investigated and/or adjusted quiet time, talk time, ground loop starts, DTMF tone issues, and everything else Keyvoice could think. We investigated the defragging as causal, PBX port and node for the VM and the customer suffering the issue. We have evaluated the underground black cable and the house pairs for the customers calling us on the problem, including moving their house pairs and the PBX node and port for them.
We ran the Keyvoice debug. (What a useless feature!) We have also run Dialogic PBXpert to verify the DTMF tones for the PBX.
This is a true cutoff. The customer goes from talking to dead air and then dial tone. There are no Keyvoice prompts. The customers have had a broad range of vocal tones. This has happened when leaving a message from our digital and analog phone sets, as well as inbound calls, analog and cellular across multiple carriers and farend PBX systems. (Yes we checked.)
We have also tried to evaluate if their is a particular dialogic card or port. We have found that it happens across all four cards and different ports.

Do you have any new ideas for resolving this?
Has anyone experienced this issue with 10.4.71?
Has anyone experienced this issue and found that the version 11.1 upgrade resolved it?
Is anyone experiencing this type of issue with version 11.x?
