Hello All,
I am new to the forum as well as to Mitel phone systems. I have taken over most work regarding our SX200 system and I have had to learn everything from scratch including making my own cable to access the system. I am able to connect to the system through both CDE and Maint.

It seems that we are able to call out with no issues, but attempts to call into at least two DID's fails with a fast busy sound. We have had storms in the area and power outages in the last two days including this phone system. I have started a ticket with our phone service provided thinking a pri may be bad or there may be something else on their end.

I wanted to also look into things on my end and do any testing to get a head start in case it turns out to be an issue with our system.

Again this system was working prior to the storms and power outage. Thanks in advance for any help you can offer.

Try a system reset. Many times a power dip or a really quick off and on will corrupt the system. Shut the system down all the way and wait, at least, a minute, then power back up.

Do you have a hard copy of how the system is supposed to be programmed? If you do and since you have already written that you can access the CDE, then go through the programming and see if everything matches.

It wasn't a quick off and on since the power was down for hours. Should I still reset and if so which cabinets should I power down and back up? The first cabinet is the main and I think the PRI card is in the second, but we also have other cabinets as well.

I don't have a copy of how it was or should be programed, but no changes have been made since the power outage.

Consider that when the power came back, it probably wasn't a 'CLICK AND IT'S ON' sort of startup, so yes do a full reset of the system.

Were the DID's, that are now down, in use and working the day before the storms 'came to town'? Are you SURE? The reason I ask is that often times we have questions regarding failure of 1 or more DID's and when we pin down the poster, it turns out that 'yesterday we programmed them into the switch for the first time and they don't work'. Often the number they programmed is outside their range and not theirs to use! And of course, there just 'might' be a problem in programming. ( )

Hey Lightninghorse thanks for the reply!

You are certainly right it may have been a "bumpy" restart. I plan to reset the two cabinets in that building in the AM.

As for the two DID's one was a fax line and the other was our main incoming DID that people use to get office extentions so I know these were working and no changes have been made.

I did find one DID today that did work. I didn't know this number existed (I don't even have a list of our DIDs...sad I know) except that I seen it in one of the forms while trying to familiarize myself with the PRI configuration. Unfortunately I don't remember the form it was listed under, but I will also get that information as well as check some additional DID's after I reset.


So far still no word from the phone co. they must really be slammed like the utilities have been in our area.

Thanks again Lightninghorse/Rcaman and I will let you guys know what I find.

Hey Guys

After the restart this morning all is working again! I really appreciate your help on figuring this issue out. Thanks to you both and have a great week.

May I suggest a UPS? They don't solve ALL problems, but they can keep a system from taking a direct hit and can provide that cushion during bumpy restarts.

Hey Rcaman thanks again for the reply. I actually have a UPS for these cabinets, but unfortunantly the outage was late in the evening and lasted for 24hours so the UPS dropped the load. At this point we don't have a generator that will pickup when the house power goes down so we have a finite period of time for the batteries to hold the load. If there were a way to gracefully shutdown and startup with the UPS communicating the ups and downs that woudl be great, but I have only seen this offered for servers. Thanks again for the help and have a great week.

I advise my customers that if this situation occurs then shut off all the equipment until the power is back on and the UPS has had a chance to get started again. Usually at least 15 minutes. When the batteries are totally used up like that the start up of the UPS is not very "clean" especially with the system trying to start up too.
