Hi Guys, I am also one of the newbies around and need to ask a question:

I've got an extension which cannot be called from an external line/place, in the hopes of recreating the extension I exported it first.
So I deleted that extension and imported it again (note it doesn’t save the keys or voicemail settings when exporting).
I got re-registered the phone and tried calling it but it showed invalid on my side, you can call it internally and make calls from it, but cannot phone directly to it from a different place e.g. cellphone or home phone. I checked those interconnect restriction numbers and they all show not restricted.
Thinking it might have something to do with DDI/DID
Another problem now seems to be that random people’s names are disappearing off the switchboard, and then IP user licence is 17 used out of total 16 licences, so they are one over the limit…
That place must be haunted…

Any ideas on what to do to get it working?

Any help would be much appreciated!

I forgot to mention it's a 3300 with MCD4.2

Thanks

Not sure what you are asking but..

If you can call the phone internally the phone is ok. If you can't access the phone from outside does it:
1). have a valid DID?
2). is it forwarded or rerouted somewhere?
3). Do the incoming DID digits sent from the Telco match the extension of the phone? i.e if your extension is 4000 then the carrier should send you 4000 on
the PRI. Sometimes they send other strings which you have to deal with be absorbing or inserting digits. You may enven have to creat a speed dial to reach the phone i.e the carrier sends you digits that don't match your extension numbers so your create a speed dial for the digits received and point it to the extension of the phone. Do you have a working phone that you can use as a reference?

What type of switchboard. If its a 5550 IP console then the DSS keys are not collected from the 3300 controller, they have to be imported in some fashion ( check the help files ).

Depending on programming you will see times when the system appears to be over subscribed in the license department.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

Hi LoopyLou... thanks for the response,

The extension was previously working so i doubt the telco changed anything, i did check the call rerouting and found nothing out of place... the phone is linked to the switchboard though but only by getting the overflow of calls and letting the switchboard reroute to it if it is too busy, but that previously never stopped it from working. i will swop out the phone to test but i doubt the problem would be with the phone as it does get calls internally and can call from it.

Where do i check to see if the that extension has a valid DID?

Yes it is a 5550 and thanks i will have a look at the DSS help files.

Any other ideas on the phone side to get it working properly again?

Thanks for the help.

There is no place in the controller where DID's are listed. You would buy a range from the telco and assign a DID to a phone by giving the phone an extension number that matched the DID or the Digits sent by the telco for the DID. i.e if the DID range purchased was 604-555-1000 to 1050. On install you would tell the telco to send a certain number of digits when a call was directed to the DID. The telco could send 555-1000 or 55-1000 or 5-1000 or 1000 for the first DID. That is what you negotiate with them. For the easiest implementation you would then assign a phone extension 1000 ( for the 4 digit example ). The controller can also absorb digits so if 55-1000 is sent by the telco you could absorb 2 digits and still assign extension 1000 to the phone. If your extension range was not 1xxx then you would create a speed dial 1000 and point it to the extension you want to ring ( say 5000 ). That's how it works. Look in the SMDR logs and you may be able to see what is being sent. Does some part of the DID number match the extension you are trying to ring? if the DID is 604-555-1030 and the extension is 1030. If not then you are most likely using the speed dial method and you should check there.

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

ChrisvanT,

Do the following command: CCS TRACE ENABLE CONT, then call the number from outside and see if your switch (PBX) is receiving the call. When you finish do a CCS TRACE DISABLE

Also check what class of service is assigned to that extension, then make sure NON DID EXTENSION is set to NO.

Give uf some feed back, Regards,


Daniel

Hi Guys, so i checked and definitly not doing the speed dial way,i went through some logs and found this one ( the faulty extension is 3201):

Log Number 1653
Severity Info
Date 2012/Jun/04
Time 14:00:14
Source Device Detection
Description An IP device, with DN 3201, registered at CDP L2 MAC address Unstable, CDP L2 Port Unstable, CDP L2 IP Address:

also then a log like this, dnt know if it has anything to do with the above:

Log Number 1199
Severity Error
Date 2012/May/30
Time 15:21:09
Source Duplicate IP Address Detector
Description Possibly 2 computers with the same IP address (172.16.0.184). One of those computers has MAC address 14:7d:c5:0d:cf:fd. If this IP is used by the Mitel RTC card, E2T card, a phone or router, there may be disruption in telephone service.

I did the CCS trace a couple times and most of them came back empty so do not know if the first one has to do with it and i dont understand that.

So what are your verdicts on all of the above and what would be the next step to do? Also the second log that complains about the same IP address, where would i find the info of the cards and their IP's? is the problem on the controller or network?

Thanks Again guys!

Let's start with gathering some vital information:

1. What's RTC IP Address (System IP Address)? What's L2 Switch IP Address, and what's E2T IP Address? You can find all this on System IP Properties

2. What's the Directory Number of the extension having issues with receiving external calls?

3. What the IP address of the phone having issues? Press and hold the volume UP key on the phone, also press and hold Down volume key, release olny UP volume, press 234, release volume down. Network Parameters YES, View current values YES, scroll down until you see Phone IP address.

Is the phone's IP address the one having conflict?

Regards,

Daniel

RTC: 172.16.0.101
L2 Switch: 172.16.0.102
E2T: Shows not installed.

Phone IP: 172.16.1.239

As per previous post DN: 3201

I dont think the phone's IP is the problem as it would've renewed from DHCP when restarted and it is able to make and receive internal calls.

Thanks for the prompt response Daniel.

What DID does belong to extension 3201? Once you now this DID number, enable the CCS Trace again and make a call to that DID from your mobile. Do you get some traces, do you see something on your maintenance command line? First of all I want to make sure the call is arriving onto the 3300.

If you happend to see something that tells you the call is arriving onto the Mitel, then we can investigate why it is not reaching extension 3201.

But again, first we have to make sure the Telco is sending that DID to your customer´s PBX.

Also, what Class Of Service is assigned to extension 3201? Go to that Class and make sure NON-DID extension is set to NO.

Regards,

Daniel

Hi Daniel,
The DID of 3201 is right, I located the next available DID (3203) and reprogrammed to that.
I then tried phoning 3203 and got the same response and issue as when it was 3201...

The COS I have set is 2 and NON_DID is set to no.

I have programmed scheduled reboot for the early hours of tomorrow morning, think the system needs a new start and maybe the dishing out of new IP's would maybe sort that conflict...

Hopefully everything just magically starts working again.

Will Post again tomorrow after the reboot.

Cheers!
Chris

So did the reboot and guess what... yeah nothing changed...

still at a loss, checked the logs again and saw two IP conflicts, though not the same as the phone's IP...

Any other ideas on what to do to get this SOB working?

Thanks

Well from mobile it just displays number unobtainable, from desk phone it says invalid and home its just dead...

Do you think the problem could be with the telco?

yep!! I think telco is not sending you the call over Pri link.

The best way to know if the call is being received over the link is by enabling CCS trace, make a call and see if you get the call details.

If you make a call and you see nothing, definetly the telco is not sending you the call.

Let me ask you a question: Do you in your country have the ability to forward a number to another destination? If this is the case try clearing that forward.

I would call the telco and open a ticket with them.

Let me know of the progress, Regards,

Daniel

Hi Daniel, I'm South African and you?

The CCS trace that was done in a previous post showed that nothing reached the controller on that DN. Yes forwarding is an option but is not configured for that DN on the controller and doubt it would be from the telco but will log a call with them to test and see if it is on their side.

Thank you so much for all your help, will post again when they give me their report on the fault.

Regards

Chris, I'm in Spain...

Definetly, call the telco... it seems to me call is not reaching your system. Maybe they have given your DID to some other customer... you never know, I've seen a lot of things from the telcos around the world, they are all the same...

Regards,

Daniel
