PRI vs SIP Trunking – Main Differences

What are the Major Differences?

 PRI

• PRI (Primary Rate Interface) is a physical connection to the PSTN over a dedicated line that only serves voice transmission.
• PRI uses a circuit switched model for making voice connections between people
• PRI has a guaranteed Quality of Service (QoS)

SIP Trunking

• SIP (Session Initiating Protocol) Trunking is a virtual connection to the PSTN over a physical line that is often shared over your existing data connection.
• SIP Trunking uses a packet switched model for making voice connections between people
• SIP Trunking is typically Best Effort

Let’s Talk – PRI

A PRI is a single line (typically a T1 connection in North America) with 23 voice channels (and a single data/control channel), that allows your business to hold 23 calls simultaneously.  This is not always equivalent to the number of phone numbers a business has.  Your business may have 100 phone numbers that are directed to come across a single PRI, however, you will only be allowed to hold 23 phone conversations at once.

 

 

Let’s Talk – SIP 

In short, SIP Trunking is a method of sending your voice connection over an existing data line, and therefore is commonly referred to as VoIP (Voice over Internet Protocol).  

Your call goes out over the SIP Trunk, is treated exactly like every other piece of data on that connection and is not given priority over webpages, emails, or instant messages. 

 

  Once it arrives at your carriers network over the SIP Trunk, your provider’s equipment knows where to direct that call; this may either switch it over to the PSTN (so that someone with a regular phone can receive the call) or perhaps send it to a PBX at another location. A single SIP Trunk is typically limited only by the amount of bandwidth on your data connection, or in some cases, limited by the number of “call paths” you are purchasing from your SIP Trunk provider.

 

 

 

 

 

 

 

 

 

 

 

 

 

Error 1606:Could not access network location Autodesk\Autocad

1606 Error + Autodesk 20xx installation + Product Initialization

We have been getting a lot of 1606 errors recently with various Autodesk products.  One suggestion that has worked to resolve this issue has been to...
1. Run regedit.exe.
2. Browse to:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

Please check for “Name” =  Common Documents defined as C:\Users\Public\Documents

 

If you cannot find registry key name and data, please add below registry information under:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

Key name    : Common DocumentsType            : REG_SZData             : C:\Users\Public\Documents

 

OR Maybe another cause

Public folder exist or not in c:\users

 

RDP: Suddenly plagued with "Because of an error in data encryption..."

Remote Desktop Connection
---------------------------
Because of an error in data encryption, this session will end. Please try connecting to the remote computer again.

To resolve this issue, follow these steps:

1. Start Registry Editor.
2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermService\Parameters
3. Under this registry subkey, delete the following values:
   • Certificate
   • X509 Certificate
   • X509 Certificate ID
4. Quit Registry Editor, and then restart the server.

Does anyone have any suggestions please as I'm at a total loss what is happening here.
Thanks.

Remove and Re-add License Key for Office 2013

---

Introduction

Having been on Microsoft Office 365 for a few months now, we started to notice that when users who had activated software on a PC were removed from Office 365, the software would go into "grace period" and would continually notify the new user of the PC that there was a problem. The trouble was I could not figure out how to reassign the software license to the new user. Finally I have found steps that will accomplish this without having to repair/reinstall office.

1.

Open Command Prompt on PC

Open a Command Prompt window, and then take one of the following actions:
• If you installed the 64-bit version of Office 2013, move to the following folder: C:\Program Files\Microsoft Office\Office15

• If you installed the 32-bit version of Office 2013, move to the following folder: C:\Program Files (x86)\Microsoft Office\Office15

2.

Display the Current License(s)

Type the following command to display the license status. Note the last five characters of any and all license keys that display in the output:
cscript ospp.vbs /dstatus

3.

Remove the License(s)

Now run the following command as many times as needed to remove all of the license keys you noted from the previous step.
cscript ospp.vbs /unpkey:<last five characters of product key>

4.

Restart the Computer

Once the remove commands are successfull, close the command prompt and restart the PC.

5.

Reactivate MS Office 2013 with New Account

Launch one of the MS Office 2013 applications (I like to use Word). The application should prompt you to reactivate the by providing your sign-on ID. Enter in the new user's credentials and the software will now be licensed under their ID.

Website Added to the Whitelist Does Not Load Completely

Issue

A website is added to the whitelist on the Palo Alto Networks firewall. However, when navigating to the website on a web browser, the page displays only partial content.

Cause

The issue may be due to the dependency, within the web page, on content from sites in the blocked list.

Details

To whitelist any website add the URL using the following format:
www.<site>/
<site>
*.<site>/

For example:
To add skype.com to the whitelist, use the following format:
www.skype.com/
skype.com
*.skype.com/

For this scenario, assume that all other sites are in the blocked category. Open www.skype.com with a browser (Chrome is used for this example). The page shows only partial content because the page calls for content from websites in the blocked category.

Resolution

Check the whitelisted web page for content references to other sites. Then, add those sites to the whitelist.

For example, using the Chrome browser with skype.com:

1. Right click on skype.com web-page and click on Inspect content.
2. Click on Network tab.
3. Reload the page.
4. Then, click on Network tab again.

Change the Google Drive default folder

Change the Google Drive default folder
Use this tip to change the default folder location in Windows
1) Click on the Google Drive icon in your system tray
2) Choose Quit Google Drive

6) A window will open up, choose Locate folder and go find the new Google Drive folder.

The system cannot log you on due to the following error: The RPC server is unavailable

CAUSE

There can be a few reasons for this problem:

     1. Incorrect DNS settings.

     2. Incorrect Time and Time zone settings.

     3. The "TCP/IP NetBIOS Helper" service isn't running.

     4. The "Remote Registry" service isn't running.

RESOLUTION

1. Verity correct DNS settings.

               Troubleshooting "RPC Server is Unavailable" in Windows
              

    2. Verity correct Time and Time Zone settings.

    3. Verity that "TCP/IP NetBIOS Helper" is running and set to auto start after restart.

    4. Verity that "Remote Registry" is running and set to auto start after restart.

•      Its recommended to reboot the computer after changing the required settings.
