Very Very Quick Quesiton about DID Problem

[DougWare]

We have a list of DIDs, but all the ones that are not in use don't ring anywhere. The caller hears one or two rings then "We're sorry, you have reached a number that has been disconnected or is no longer in service", our standard telco message.

Does this indicate a DID problem, or a PBX programming problem? I'm pretty sure that I have the phone extension programmed correctly...I just want to make sure before I call the telco.

Thanks!

1. are they paid for and activated by the Telco?
2. have you programmed them to ring at a set?
3. have you programmed the trget line with the right received digits?

They should be activated at the telco...

I believe they are programmed to ring at a DN (see below).

The DN is set with the last 4 of the received digits, just as the working DIDs are assigned to working DNs.

That only leaves a telco issue, correct?

Sounds like they may be de-activated at the telco. If you have active DID's that are not in use, you should normally get a fast busy when you dial into one. The phone system will send out a fast busy because it has no destination in the system, but is absorbing the digits. If you are getting a telco message, they have done something to your DID's and you will have to deal with them, unfortunately.

Not necessarily so, IF your DID numbers arrive via PRIMARY ISDN, then that is certainly possible because with the communication on the DCH, if the DID number(s) is UNassigned in the Norstar it may be sending an unavailable status message to the CO switch when calling that number(s) during the call setup process. I know this to be true using PRI on Avaya systems, but have never had access to a Norstar with a PRI to verify how Norstar's logic works for this situation.

Anybody else tried or have input on this?

If the prime for the trunks are set to none then you could get this message. If you want to have the unassigned DID's ring some where then make the prime on the trunks the main phone . Then when a call cames in for one of the unassigned lines it will be directed to the prime set .

When I went to a PBX Class in '96 we were advised that the FCC requires the PBX to terminate all unused DID calls. I set a hunt group to forward to voicemail and make an info mailbox with the hunt groups DN, recording: "You have reached an unassigned number at XYZ company, please check your number and try again." Then have the hunt group pick up all the unassigned target lines. Works out ok and dosen't use resources since an info mailbox dosen't require a keycode.

The downside of answering UNASSIGNED DID numbers is the calling party get charged for the call. Left unassigned the Telco provides the appropriate recording and NO charge! Also no BCH is used since the call is not even sent to the Norstar.

The FCC does not always know what they are doing!

I usually use curly's suggestion. I've never tried yours, though, jerry. Most of the inbound calls are going to be wrong numbers and telemarketers, so that wouldn't trouble the staff.

 

[jerryreeve]

sysquest, I don't think the telco gives a recording on unanswered telco calls, ATT gives you a long pause then a timeout fast busy.

I had one customer that lost a few blocks of his DID's he said that he was told that because he was not terminating or using them they reverted to the available pool. I couldn't get a verification on this from telco but it sounds kind of odd to me.

I agree about FCC.

If #s r in reserve and not programmed in the MICS, I usually get "the number is not in svc

 

[jpanzer]

But, programmed in the MICS, it will give fast busy, if no destination. We have an MICS with PRI at our office. We have some DIDs that are programmed in the phone system, but have no destination or hunt group, but those numbers are ours for future use. When we call into one that is not used, it times out with a fast busy.

Also, dealing with the telco to get DID's activated is a pain. That's why you keep them active and assign later.

jerryreeve,

Unless a call is completed, answer supervision sent, there is no charge for the call. In the case above, a call sent to the AutoATT/VM is a completed call. For unassigned DID numbers it depends on the message sent to the CO switch during call set up form the Norstar, and how it treats that condition as to whether you get a recording or a fast busy (120IPM).

As far as DID numbers disappearing, once they are in the Trunk Group and are billed, they should not be removed by the Telco without notice to the customer! If they are held in reserve that is a different story and policies vary. I think the keyword is are they being billed for them.

In dealing with Telco for DID numbers, yes they can be a pain, but it boils down to planning and research and knowing how the service provider does provisioning, and how to order them properly. These are things that most customer have no clue!
