Summary
200ICP embedded voicemail fails to answer.
Question
Why does my Embedded voicemail fail to answer?
Answer
Sites may experience embedded voicemail failing to answer. Sites in this case would typically in the hospitality market. Those whom would use tcp port 6830 where the PMS server connects to the 200ICP controller's voicemail system. All sites whom have had this issue all have used the Precidia Ipockets for SX200 ICP to PMS integration.
Only a system reboot will recover the Embedded voicemail functionality, and even when doing so, this problem generally will return. Using the start and stop commands from secure port 2002 shell for the embedded voicemail does not resolve this problem.
When troubleshooting a site which meets the symptoms and details outlined above, the easiest way to validate that this bulletin relates to the site is as follows:
1-From port 2002 (secure telnet)
2-Enter the following command: inetstatShow
Search through the output for a line similar to the one below:
-> inetstatShow
inetstatShow

In the output above, this identifies that
VMPMSSrv is the process
4404 are the amount of errors in the Send Q at the time, and will keep growing and the problem will soon occur. (data has proven that once this reaches 8000 the voicemail will no longer answer).
10.40.196.4 is the ip address of the 200ICP
10.40.196.5 is the ip address of the Ipocket for the PMS to voicemail connection.
The only known solution to this problem has been resetting the actual Ipocket that uses port 6830.
The Ipocket that is used for the PMS to 200ICP is not affected by this problem. It does not need to be reset.
Precidia has not reported any known problems with the current units or firmware. This problem was not duplicatable in the Mitel support labs. The information and workarounds are based on site investigations and run time after resetting of the Ipocket.
I suppose you're entitled to your opinion, I'm just not going to suppose very hard.
