Saving WAV files for PABX/TPG Bizphone

Saving WAV files for PABX systems

Users send audio file from phones and pcs in all different formats

Using Audacity  you can transcode to a basic WAV file for PABX  and TPG Bizphone

1.     Download Audacity here
2.     open the sound file in audcity
3.     Trim out silence at the ends and adjust the volume  (Effect  >Amplify)
4.     If stereo, click above Mute/Solo and choose Tracks > Stereo Track to Mono.
5.     Set Project Rate (bottom left) to 8000 Hz.
6.     Go to File > Export Audio…
7.     Choose WAV
8.     Choose WAV (Microsoft) header.
9.     Choose “U-Law” Encoding (this sets 8-bit, and 8 kHz).
10.     Edit the file name and be sure it ends in “.wav”.
11.     Click Save.
12.     Use this Website  https://g711.org/  to convert the file

   

Then load in PABX or TPG BizPhone

Uninstall 

To print from 32-bit apps enabling Direct Printing for your printer using the following procedure:

Open an elevated command prompt and run the following command to find if the feature is already toggled on (replace PRINTERNAME with the name of your printer):

 rundll32 printui.dll,PrintUIEntry /Xg /n PRINTERNAME

If Direct Printing is not enabled, run the following command from the same elevated command prompt (replace PRINTERNAME with the name of your printer):

rundll32 printui.dll,PrintUIEntry /Xs /n PRINTERNAME attributes +direct

To print from 64-bit apps on 64-bit OS or using 32-bit apps on 32-bit OS, you have to download and install the Application Compatibility Toolkit to apply the PrinterIsolationAware fix to affected applications using the Compatibility Administrator tool.

UPDATE  the supported channels is not correct due to a bug in the WLANPI profiler not taking into account of the regulatory Domain.

Supported 5Ghz Channels

Trying to work out if there is a way for the profiler to determine the country code.

The profiler could use the country code from  /etc/hostapd.conf on WLAN PI   ?  the user would need to set correctly 

here is pcap  https://www.dropbox.com/s/zjtf02k3atlej2y/4a-d3-49-71-07-c6_5.8GHz.pcap?dl=0

I saw this 

https://patents.google.com/patent/US20080259882A1/en

Could 802.11d help here....

IEEE 802.11d-2001 is an amendment to the IEEE 802.11 specification that adds support for "additional regulatory domains". This support includes the addition of a country information element to beacons, probe requests, and probe responses

Not seeing this in the pcap

And was asked by Josh Schmelzle try and get the Phone to connect to channel 124

I tried to set the WLAN PI to channel 124  in hotspot mode using the comfast adaptor  regardless of country code this was not possible   (and should not be possible is Australia !)

Fixing Windows 10 Boot after Ghosting 2 disks

 I love Ghost but it is getting old now and does not set the MBR when finished for windows 10

Once Ghosted you need to fix the boot records on the new SSD

Windows 10 USB Boot  --> Adv --> Command prompt

DISKPART

LIST DISK

SEL DISK 0

LIST VOL

SELECT VOL3 (the EFT one  99mb fat32) 

ASSIGN LETTER=H:

SEL VOL 1  (the windows disk)

ASSIGN LETTER=F:

BOOTREC /fixmbr

BCDEDIT /SET {bootmgr} device partition=h:
BCDEDIT /SET {default} device partition=f:
BCDEDIT /SET {default} osdevice partition=f:

And reboot !

RDNSS with IPV6

I was trying to get my Meraki AP on IPv6.  It seems the AP does not support DHCPv6  (and will not any time soon I have been told on forum)  Android devices also do not support DHCPv6  and rely on RDNDSS.

Windows 10 will only use RDNSS if there is no DHCPv6 or DHCPv4 server. To get RDNSS to work on windows 10 need to disable DHCP IPv4 and DHCP IPv6.  So for the best compatibility in a dual stacked environment you need to have DHCPv4 and DHCPv6 add RDNSS for segments with android and Meraki devices.

I thought DNS option were only supported on DHCPv6  but they supported on RDNSS  rfc8106

This allows RA DNS options to distribute DNS server information as part of RA advertisements.
