Hotel with a Mitel SX 100 experienced a power outage that lasted a while. When the system came up none of the calls go to their voicemail. Being familiar with the newer SX200 ICP Controllers I checked call re-routing. I can call the voicemail directly so I believe the voicemail to be in good working order.

Thanks in advance.

System came up in night mode after the reset. Try day mode & see what happens.

When you say SX-100 with voice mail, I assume that they have an original Mitel 3rd party processor card, such as a Generic 319 card. Finding Sx-100 techs with there faculties still intact may be difficult as this was discontinued in the 80's. But, it still is a workhorse. Voice mail intergrationis was very complicated and you may have lost the programming.Or, as the Doctor says, maybe you should set the console to Night 1, a common setup back then..PM me if you need more help

So why would the extensions be affected by Night 1? When a caller calls an extension vm doesn't answer either.

What happened is that you probably lost all the call forwarding. If you do have a 319 you can do a blanket call forwarding I believe. The 319 was a retrofit solution which allowed DTMF integration to voice mail. Someone out there probably has manual sheets on this. If you can't find one I may be able to find one around here but it would take some searching.

There was also a late upgrade from Mitel that was designed to ease vm integration. It was truly an upgraded 217, but was occassionally referred to as a 218. So first, open the door and look at the processor (the card with red pulls) and see if it says 217, 218, or 319. Then, get back to us. Or, push and hold 'Ident' on the console and see what it says on the upper right numeric display. Then get back to us. Yp, I'm one of the 100/200 techs whose faculties are generally intact, altho I am retiring June 1. John C. (Not Garand)

Well, you think you're retiring, but you'll be here. You'll be posting. And although I know my way around a 100, that's all I'm giving up for now. Roger, what happens when you call a room that's busy or doesn't answer? Does it go back to the console? What Dane and Lightninghorse are saying is correct. Check your call forwarding. PS, easy now Phonedrone, time passes quickly!

After I posted, I got to thinking (Yep, I can still cogitate) His batteries are shot and the processor went dumb. But, I'm trying to figure out how it remembered the extensions. Assuming it's a 319, will they default with ext numbers like a 20 or 50? I have 1 I've been playing with, but not enough.
And yeah, I'll still be here. Who knows, maybe I can drum up some remote support jobs that pay more than 'Thanks'. Got a garage full of stuff to clear out, and a FIERO in semi decent shape that was parked running 3 years ago. Price was right, $250. I could salvage it for that except for the fact that it's plastic on the outside. And the riding mower that won't move, transaxle problem and my retired labor is a WHOLE lot cheaper than a new 42" mower! So, I can probably stretch that out for a couple of years. John C.

The calls ring and... ring... How do you turn call forwarding back on? I have checked the Feature access codes and I don't have a CF NA or CF BNA.

You have to do only CFNA no CFB.

From each extension (in the room or on the 66 block)

Look if this is a 218 or 319 there is a global call forwarding command - other than that on the old analogs there is a specific feature for call forwarding busy - no answer -which takes care of both conditions - you can not enter them separately. Get into programming and look at feature access code 46 - should be able to dial that code and the forwarding destination (which in this case is going to be a speed dial location. If you then go to check on the console to make sure the forwarding is done it will not show an ext number instead it will show ext (for external - which may be a bit confusing) >Likewise if you dial the number from the console (or superset if there is one) when the ringing times out or if the extension is busy it will flip over to say EXT on the display.

Good luck - the toughest thing may be finding out what the forwarding speed call number is. You need to get into extended programming and utilize the correct console overlay. Other than that I assume you know what people dial to retrieve messages so if the original programmer was any good it might be near the same - say if they dial retrieval code of 55 you might try dialing 56 or 57, etc and see if you hit the voice mail (you will get different message than when you retrieve. At that point you can test forward on ext and then dial it to see if you get the correct "leave message" recording. If you do then just set the forwarding up on the rest of the exts.
