MiVoice 400 DoS Blacklist

Asstra 67xxi phones ceased to function for a while and then resumed working. Under Event Logs it showed the phone was Blacklisted (often repeatedly) for DoD reasons. The following seems to have fixed it:

Set the Keep Alive to 120 and registration timer to 3600. 

MiVoice 470 ISDN Dial up Access

1. Setup ISDN Modem
2. Mitel 400 -> Configuration -> Routing -> Select a DDI number

-> CDE = Remote management (SRM).

3. Create a user for Admin access or use existing user.

4. On Windows -> Create a VPN (Set up a connection -> Connect to a workplace)

-> Number = DDI number, user and password = as per that on the A470.

5. Connect. Use ipconfig /all to view assigned IP address.

6. Open a Web browser and enter the VPN IP of the PBX.

MX-ONE Number Presentation 2

On a client using a Primary Rate ISDN, the CLOP was incorrect because the circuit numbering "clashed" with the extension numbering:

- 3125xxx is the DID range.
- 5xxx is the extension range (thus no DID tables need to be setup)
- 31255xxx is the resulting displayed CLOP

number_conversion_initiate -conversiontype 1 -numbertype 10 -entry 5 -truncate 1

The above removed the extra 5 for each extension as they call out.

It is worth noting that:
1. I did not use RONDI.
2. I set the Public Exchange number (=312) and Common Public Directory Number (=312) in the Web GUI (MTS)

A470 Voice recordings with Linux

Normally to get the correct CCITT format, one has to use Windows Sound Recorder. However, as brought out at http://forum.epygi.com/showthread.php?2444-CCITT-A-Law-conert-with-Linux, it can easily be done with the Linux command line.

Therefore (using Linux only):

1. I recorded with Audacity.
2. Exported the Audacity project to .wav
3. Converted the file with sox input.wav -A -c 1 -r 8000 output.wav
!Update: sox input.wav -e a-law -c 1 -r 8000 output.wav

It is interesting to note, that converting the .wav with MS Sound Recorder produced distortion, whereas the conversion with SOX was crystal clear.


A470 audio file format: CCITT, A-Law, 8kHz, 8bit, mono.

Mitel MX-ONE Missed Call / Call List on DBC442202

The MX-ONE web interface for configuring the IP phone config files does not provide the option to enable Call List (Missed Call) on the programmable keys of the DBC 442202.

The option can be enabled manually:

Got to the root folder of the web server (where the IP phone files are stored).
Backup the existing d42x02-config.txt file.
Edit the file:

[FunctionKeysDBC422]
Settings=5
CallWaiting=8
CallBack=1
CallList=9
Transfer=2
FreeOnSecond=3
MessageWaiting=7
Conference=0
EnablePBXStoring=YES

The IP phone will have to be restarted so as to read the new config.

NEC SL1000 Telnet access

To be able to run ping and more:

10-20 Item 6: Set DIM Output port to TCP Port 23.
90-31 DIM Access: Enable, set username and password.

Possibly a System Initialisation -> 2nd Initialisation will be needed.

Mitel MMC and SIP trunks

Some SIP providers do not recognise '+' in the numbering. So if the MMC is battling to receive calls out of office ("blue" registration), the problem is the '+' numbering. Change the number to '00' on the Controller Web interface and the host communications server.
