Phone Flashes "DRT"--Doesn't Ring 1

[PTerrell]

System: MICS 6.0 on a PRI

Symptom: On inbound external calls, the phone at x2036 does not ring. I can see "DRT" and something else flash on the display panel. After one ring, the call ends up at x4000, which is a VMI. The VMI, through DMTF, reports that the call came from x2045. On internal calls to x2036, the phone works correctly.

Background: This may be a red herring.
As I was experimenting with virtual DNs and the VMI, through a Change DN, I made this phone x3000. I also played with having the VMI at x3000. Unfortunately during these experiments, I forgot that a CCR mailbox was already at x3000. I worked with my Norstar installer about fixing that mixup, but the installer can't figure out this problem--he's getting an ulcer from working with me. :-(

just turn drt off on this phone.

Sounds like your target line for 2036 may not be working quite right. I would look there first, since internal calls are working properly. It is rare, but I have also seen a target line go bad. You might have to set up a new target line.

look in line data of programming. c if this line is set to drt.

Hi Nortellian,
I can't find any settings for DRT and I don't see this in the "wonderful" Nortel docs. Can you point me to what I'm missing?

Hi Marv01,
Would copying the line information "fix" the problem, 'cause that what I tried to do.

Are there instructions on setting up a new target line? Again, I'm not seeing instructions that guide me on this, but as I newbie I feel very "blind".

Thanks,
Paul T.

check under system programming than feature settinings.

 

[Nortellian]

If you look in the installer manual and do a search for drt this sounds exactly like whats going on with your line.

Your DRT is a system wide setting. That part is probably just fine. The call probably made it to Ext 2036 via DRT if the REC digits did not match the DN. Look and see what target line is assigned to 2036, and then look at that target line to see what the digits are, and what the prime set is. Also, do not try to copy target lines. Each one is unique.

Marv01 is correct. Check your target line number. The T-1 is just open conduit for incoming and outgoing calls. The carrier 'knocks' on the norstar's door and says, Hey I have a call, anyone home? We WINK back and say, yeah, send your digits. The Telco then picks an available channel (any one of them) and sends digits (usually the last four digits of the DID number).

We receive those digits on target lines. On 6.0 SW they start with 157. We then assign the target line to whatever phone or device we want to have ring.

Therefore, if the DID number is 813-222-5555 and Telco is sending 4 digits, I would program target line 157 to rec'd digits: 5555. Then assign 157 to appr&rng on ext 222.

Call comes in; telco sends 5555, we take them in on 157, 157 is on ext222; ring the phone.

IF either telco isn't sending the digits or we don't have a target line receiving those digits then the call will ultimately end up at the PRIME set for the channel.

That's why we are thinking it is a problem with your target line or the receive digits. Because you are saying it is showing DRT to Prime. (Delayed Ring Transfer)

Thanks all for the quick and clear advice. I was unable to get over to the branch office until now.

I see under Lines that Line193:2036, with Rec'd #:2036 and prime set 2036.

If the target line 193 has gone bad, do I create a new line? I guess the new line would be line 248. I then clear the Rec'd # and prime set from line 193, and put that info on line 248?

Thanks again!

 

[mroberts]

Go under Terminals&Sets and make sure that target line 193 is assigned to appear and ring on ext2036.

Problem solved, but now I've got a "mystery"...

I checked under Terminals&Sets for x2036, but no lines were assigned. I checked the surrounding extensions, 2030-2044, and none had a line assigned. But those extensions were working fine--the phones rang, call forwarded to the VMI, and gave the correct DTMF.

But x2045 had an appear&ring on line 193. I removed line 193 and x2036 started working correctly.

So that gives me two questions:
1. Why are x2030-2044 working without a line assigned?
2. Should I add the appropriate appear&ring for each extension, or let it go?

As a side note, the extensions in the original working rage of 2000-2029 all have the ring assigned on the appropriate extens

 

[mroberts]

When you call into those other extensions that are working without line assignment; do a feature *0 and press the button that is ringing. What does it say?

Hmmm...If I follow your instructions exactly, I get "Release Calls". So I don't think that's what you meant.

Here's what I get if I press F*0 on the button that a call rings on, along with what button it's ringing on (these are T7316 phones):

x2036: the extension that started the thread
Rings on 4th button down on left
F*0: 193 2036
Softkey "Show" says Not redirected

x2033: in the range of phones without the line assignments
Rings on the bottom right button
During the ring it displays "2033 to prime"
F*0: 2033 2033
Softkey "View" shows Port 403

x2021: in the range of the first phones setup on the system
Rings on the 2nd button from the bottom on right
F*0: 2021 Rhonda
Softkey "View" shows Port 122

I hope that I'm not providing too much detail...

Thanks much!!
