Mitel 5312 and 5324 in SIP mode

Mitel sell the 53xx range of phones as 'Dual Mode' meaning they can be switched to SIP mode. That's great, except for the lack of support and documentation available.
While there are user manuals for the 5320 upward, the last manual for the 5312 / 24 was published in 2007, and as for configuring the phone, that is largely undocumented.

Here is what I found got me working. If you are a dealer or have a Mitel 5000 (MiVoice Office) on the latest software (6.2) then that will help.

Two ways to start.

1. Upgrade on a PBX.   The Mitel 5000 has a tftp server built into it and will upgrade any phone attached to it.  Boot the phone into config mode and set the tftp server as the IP of the phone system. When the phone restarts it will receive the latest build for the phone.

2. Upgrade from the TFTP server.  You will need to get the SIP software from the Mitel website. This is an area protected for dealers with Mitel accounts, and there are 3 archives with different software in for the different phones.

Switch into SIP mode.

This has (?) to be manually done on the handset.  Boot the phone holding down the Superkey and then press * to configure the phone. In the 'Phone Mode' menu you can switch to SIP and another reboot gets the phone into SIP mode. In SIP mode a web interface is made available that is not there in Minet mode.

Once the phone boots it sits there asking for a user id. If you type a user ID in it will attempt to get a file from the TFTP server.  If you type in 1234, then when the phone reboots it will try to get a set of files.  The first will be called MN_GENERIC.cfg, the second includes the user id and is called MN_1234.cfg, The phone then tries to get one with its mac address included in the name MN_macaddress.cfg and lastly it tries and fails to get a US language file. (This is why i recommend an upgrade to latest version. Earlier versions gave up when they couldn't get the language file).

The phone can be given information about its account and tftp server in several ways. DHCP option 66 will probably do it. You can type it into the phone using the bootup menu, or you can browse to the phones web interface and define it there.  You can find the IP for the phone an the admin tools menu of the phone when it is booted up.

I got as far as getting my phone to tftp what looked like a good config from the tftp server, but still couldn't make a call. Any attempt to call resulted in a 'No Proxy Defined' message back on the display.  A google search turned up no answers.  So here is the answer you may be looking for.  When you define a user in the user list, you also have to have a matching user defined on one of the line keys. Check out the config below. Mitel have an example config and spreadsheet of values that can be used, but its not obvious.

MN_Generic.cfg  -  This will be requested by all Mitel 53xx phones (and others) and contains global information. It could be missed if such info will be included in the individual files.

Change to Windows mapped drives - Caught me out when saving from Mitel interface

We have been making a move to use Windows 8 and 10 on our laptops and have found a problem with the Mitel System Administration and Diagnostics software and other pieces of software that use mapped drives.

Each user has tended to map their own drives, but while they appear in file explorer, in another program when you go to save, the mapped drive may not be there.

This turned out to be due to some programs automatically running as an administrator, and then not being able to see the drives mapped by a user.

To fix this

• Open an elevated command prompt (Right click on Command Prompt and 'Run as administrator).
• Map the drive again using the Net Use command.

An example net use might look like

Net Use y: \\192.168.1.2\Share /USER:mydomain\username mypassword /PERSISTENT:YES

This will map a y drive that goes to the server 192.168.1.2 with a shared folder called share.

I hope this helps another user out.

Mitel 3300 MCD MiVoice Business One touch divert

The user wanted a button that would always divert their phone to their mobile and one that would lift the divert, no matter what they had done in the forwarding settings on their phone.
Here is what we did.

Create a speed dial for their mobile e.g.  100 = 07989654321
Check the Call Forward -Third party code (*65 on this system)
Check the Cancel Call Forward -Third party code (*75 on this system)
Check their extension number (220)

On a key on their phone set a user speed call of *65 220 100 (miss out the spaces) to divert
On the next key enter *75220

Maybe it seems simple to you but it took me a while to get there!

Mitel 3300 MCD MiVoice Business Telephone directory and digit blocks.

We have a customer who wanted to recognise their customers CLI and match a name to it for display the handset.  I know it seems a bit old fashioned, but it's what they wanted. The have an MXE. The problem is they wanted to enter 4,500 of them.
I found I could import 1700 of them before it gave up. Looking at the system usage of the database dimension, I could see that it was not lacking in directory entries, it said it could have 20000 of them. What was lacking was digit blocks. The default is 12000 digit blocks.
I had to take a backup, re dimension the database to allow 20000 digit blocks, do a reboot, restore the database and reboot again to get more space.

If you don't know what an alpha tag entry should look like to do directory matching then it is in the format "Access digit, Tilde, full number".  So if the customer is at 01245 406 407 and you dial 9 for an outside line, your directory entry would be

 9~01245406407.

If you don't receive a leading digit on an inbound call then move the tilde along.

90~1245406407

The number has to be dial-able via ARS or the entry will be rejected.

System Slowdowns and CPU running 100% - Mitel 5000 / MiVoice Office 250

One of the most frequent complaints we get is that of system slowdown. So the user may report that when the phone rings and they lift the handset, that it takes a couple of seconds to answer, or that the display on the phone changes slowly, or when they dial digits they take a few seconds to register.

This is usually caused by the CPU being run at or close to 100%. The avaerage system usually ticks over averaging 20 - 40%, so seeing the processor flat out for a prolonged period rings alarm bells.

Most Common Causes We Have Found

1. Sip Hackers - The number one cause. 90% of issues turn out to be this. All versions of the 5000 have a SIP port 5060 open by default, even the versions that did not support SIP trunks or extensions had a SIP port. If this is open to the internet without a firewall filtering by source IP then your system will get bombarded by call requests, sometimes thousands a second. Even though the calls don't get placed, the effort of responding to them causes the system to slow down.  You can see the messages if you turn on SIP logging. Either lock down SIP using the firewall or turn of the SIP port in IP Settings / advanced
2. SSH Hackers - The same thing will happen if you leave port 22 open to the internet. Some Bot will come along and bombard the system with login messaages trying to find the password. You can see the fail messages in the syslog.  Either lock down or turn off SSH.
3. Voice-mail to email - Whilst it usually does not cause too much of an issue, sometimes the site are heavy voice-mail users and have extended the recording time available per message, or worse yet are using the embedded voice-mail for record-a-call.  The turning of the voice-mail into an mp3 then emailing it can cause the processor to show heavy loading. I tested this once with a 20 minute call recording and it took the processor an hour of running flat out befoire it calmed down.
4. SSL Problems - Getting a bit rarer now, but we have found a site where an SSL error was being shown in the exception log. Using the web interface of the system the certificate was regenerated and the web server restarted. This must have unlocked an internal process as immediately the processor use dropped.
5. ISDN Errors - Whilst Open reach are usually insistent there is no error, we have seen circumstances where ISDN can flood the system with error messages causing the system to slow down as it attempts to handle them all and record them in the logs.
6. Over use of G729 - One of the most common mistakes engineers make which causes load on the CPU and can affect voice quality is to use G729 where it is not necessary. G729 should only be used where there is a real issue with having enough bandwidth for G711. On the LAN where there is bags of bandwidth it is never needed. Even on broadband you may not need it. G729 compresses the speech, which while saving bandwidth, requires more resources on the CPU to do the compression/decompression, so whenever I see a high load on a CPU I look to change to G711 and this usually has a visible effect on CPU use.

I hope this may help someone in the future solve a problem!

FreePBX, Asterisk inbound DID restricted to multiple CallerID's

Recently we have been doing a lot of work with FreePBX.  This is an Asterisk distribution and FreePBX is the web interface that writes the Asterisk dialplan.

It was easy to get a DID to ring in to our system, you can do that through the web interface just by filling in the boxes.
Then we were asked to restrict that DID so it only allowed a certain caller to access it.  Again that is fine, there is a caller ID box in the web form that allows you to do that.
Then we were asked if two callers could have access.  This is trickier as the Caller ID box on the inbound route form only allows one number to be entered.  But we created two inbound routes, both with the same DID, but different CallerID's and again this worked, now two phones could dial in on one DID.

Where it started to get unmanageable was when we were asked if there could be 20, 30 or 40 CallerID's with permission to call that DID.  Whilst we could keep creating inbound routes, the menu structure of the web interface was going to start getting very messy showing all those additional routes just for 1 DID.  Because of this we started looking at how to add these into the custom files that are hidden from the web interface.

Here is what we did.

Use WinSCP to connect to the PBX.  WinSCP allows the transfer and editing of files on a linux box.

Navigate  to /etc/asterisk/extensions_additional.conf     -    Don't change anything in here as this is a file FreePBX writes and any changes will be lost.

Open the file and do a search for your DID number, you will see a section like the one below.

[ext-did-0001]
include => ext-did-0001-custom
exten => fax,1,Goto(${CUT(FAX_DEST,^,1)},${CUT(FAX_DEST,^,2)},${CUT(FAX_DEST,^,3)})

exten => 01161234567/07971234567,1,Set(__FROM_DID=${EXTEN})
exten => 01161234567/07971234567,n,Gosub(app-blacklist-check,s,1())
exten => 01161234567/07971234567,n,Set(CDR(did)=${FROM_DID})
exten => 01161234567/07971234567,n,ExecIf($[ "${CALLERID(name)}" = "" ] ?Set(CALLERID(name)=${CALLERID(num)}))
exten => 01161234567/07971234567,n,Set(CHANNEL(musicclass)=default)
exten => 01161234567/07971234567,n,Set(__MOHCLASS=default)
exten => 01161234567/07971234567,n,Set(__CALLINGPRES_SV=${CALLERPRES()})
exten => 01161234567/07971234567,n,Set(CALLERPRES()=allowed_not_screened)
exten => 01161234567/07971234567,n(dest-ext),Goto(disa,1,1)

;--== end of [ext-did-0001] ==--;

What this section of the dialplan does is handle calls in on 01161234567 that have come only from 07971234567.    Notice the include => ext-did-0001-custom .   This causes the PBX to look for another section called [ext-did-0001-custom].   At the moment this section does not exist and we cant put it in this file, but we can put it elsewhere.

Navigate to /etc/asterisk/extensions_custom.conf     -     You may well find this file is empty.

Copy the [ext-did-0001] section and paste it into extensions_custom.conf

Change the section name to be [ext-did-0001-custom] and don't forget to change the section end marker to look the same.  Take out the include statement You can now do a search and replace on the CallerID, it will look like this.

[ext-did-0001-custom]
exten => fax,1,Goto(${CUT(FAX_DEST,^,1)},${CUT(FAX_DEST,^,2)},${CUT(FAX_DEST,^,3)})

exten => 01161234567/07989876543,1,Set(__FROM_DID=${EXTEN})
exten => 01161234567/07989876543,n,Gosub(app-blacklist-check,s,1())
exten => 01161234567/07989876543,n,Set(CDR(did)=${FROM_DID})
exten => 01161234567/07989876543,n,ExecIf($[ "${CALLERID(name)}" = "" ] ?Set(CALLERID(name)=${CALLERID(num)}))
exten => 01161234567/07989876543,n,Set(CHANNEL(musicclass)=default)
exten => 01161234567/07989876543,n,Set(__MOHCLASS=default)
exten => 01161234567/07989876543,n,Set(__CALLINGPRES_SV=${CALLERPRES()})
exten => 01161234567/07989876543,n,Set(CALLERPRES()=allowed_not_screened)
exten => 01161234567/07989876543,n(dest-ext),Goto(disa,1,1)

;--== end of [ext-did-0001-custom] ==--;

You can now save the file and then close it.

If you now ask asterisk to reload the configuration you will get in from two different CallerID's.  You can keep on adding further DID definitions with other CallerID's into this section and they won't show in the web interface of the system.

Mitel CSM contacts list format (Callview)

I came across this question today from a customer;

'What is the file format of the contacts import in the CSM server?'

When I looked for the answer it was buried deep in the help file of the CSM Server and not at all obvious.
The file is a six field csv file.  The format is,

Phone number or email, Name, Custom field 1, CF2, CF3, CF4

So a phone number entry might be

01165291911,Bobs Hardware,Bob Hammer,512345

An email contact is defined by an @ at the beginning of the line, so it might look like

@sales@bobshardware.co.uk,Bobs Hardware,Bob Hammer,512345

The fields are matched on calls and emails and the custom fields can be included in reports, so for instance including custom field 2 in the report might result in the customers account number (512345 in the example above) being displayed in a report or used in a routing rule.

The amount of characters allowed per field is set as 255,50,50,50,50,50
