If anyone can help i have a customer who has a Starplus STS and they are asking me to help them with a problem. They keep dropping calls during the middle of the phone call, is this a problem with the system or the service provider? And second they cannot access voicemail boxes that they could access 2 days ago. If you can help i would appreciate it.

Thanks
Shawn

Is it randomly dropping on different phones ? One phone in general ? One line ? All lines ? If it is one line then you should switch with another line and see if it follows the actual line or the co port on the system. The voice mail sounds like user error. When you say "access mailbox's" do you mean by pressing the vm button, remotely accessing, or something else ? Could they e forgetting the password ? At what point does the "access" fail ? We could answer your question with more details.

I would go into the voicemail system as an administrator and check the configurations in the mailboxes in question. When a user does there own programming in the mailbox they often enable or disable features for that mailbox not really knowing what they are doing. Just a thought...

I am getting a similur problem.

I have a Vodavi Starplus 7000 DHS not DHS-E system. This problem just started about a week ago and nothing has changed with the amount of people or the CO lines or stations.

I have a sales force team of about 11 people with 9 CO Lines. The problem seems to occur around the same time of day now about 2 pm.

It seems to happen when 4-6 lines are in use.

We can tell when the system is about to fail. The warning sign is that when we get an incomming call you try to answer it, it doesn't anwer/pickup the incomming call.

Then all the calls that people are on get dropped and the sytem is down for about 3 seconds and comes back up.

I did a test on the system by pushing the CO Lines in Order, backwords and every which way and one line the one I started with wouldn't work anymore for about 5 min then it would work again.

Do you have an options card in the system? It can cause this problem.

I really do not know how can I tell?

I looked at the sysem and gooled the options card, I do not have the options card installed.

That system is notorious for such behavior when the memory retention battery is failing. It's weak enough for the database to be slightly corrupt but not so dead that all programming gets lost. Vodavi's newer systems won't function with a dead memory battery. Since your system is easily 10+ years old, it's probably time for a battery replacement. It's not a field-replaceable battery, but you might be able to find someone willing to try it.

Otherwise, the system would need to be sent to a repair facility. Of course, this would mean no phones for quite a while, so I doubt that will be an option.

The DHS is a pain. I installed lots of em and grew to hate every one of them. It isn't an LG system like other Vodavi products. I wouldn't think replacing the battery would be any harder than replacing a Triad-s battery. Just wiggle the old one off the motherboard and solder a new one on. The STS that is dropping the calls...make sure the CID module on the mainboard is nice and snug, if not you will get crosstalk and or dropped calls.

I have two units with the exact same configuration. I replaced one with the other and that one experiences the problem more than the other so could the batteries still be the problem.

You might want to check the loop current of your lines. You need 17-22 milliamps on each one while on an active call. If you have less it may cause the DHS to drop the call.

Ok, I did a test on the phone lines I have 9 hooked into the system.

My line 3, 6, 8 , & 9 lines show me 6.8 milliamps and all other lines show me 17 - 30 milliamps while on an active call and if one of thoes lines is acitve all lines show me 6.8 so this is very well the reason why my DHS is dropping all the calls.

So my next question is how do I fix this problem?

One other thing I did switch out board to see if that was the problem and I get the same results with other board.

I am having a very similar problem with my Vodavi Starplus DHS system 'hiccupping' and resetting at night.

It has a 6-port CO Module (though we only use 4 CO lines), an MOH/BGM Option module, and a 2 Port SLT Adapter.
For the past few years, the system will work well throughout the work day, but at night between midnight and 8 am, it will begin to 'hiccup', with the displays going blank on the executive handsets intermittently. This continues till the system resets to Jan 1, 1997.

Although it loses its settings, the various handsets will have strange problems until I turn off the power and toggle the memory battery backup switch.

Has anyone heard of a phone system reacting like this on such a regular basis--always at night? We do have an APC battery backup and surge protector serving all the equipment above.

This original thread is over a year old. Everyone prefers that we start new threads in such cases.
That being said, I would still start by replacing the Varta 3.6V memory support battery. You have it on a UPS but unless the USP is on-line and a true sine wave, you can have a brief instant where a weak battery won't hold.
