I thought I would give this a shot before I have to call someone..

 

We use a NEC DSX-80, which is a very old phone system. When a call comes in our main line, dispatch will transfer that call. However, it is dropping the transfers just about every time. I have no idea where to start. I have rebooted it, and the issue is still there..

Internal extensions. 

 

Well that's interesting then, so it's an external call, answered by dispatch and then transfered to another internal DN. Does the phone being transfered to ring at all or once you try to join the call it drops?

Also, are the internal extentions on in the same building, on the same port modules etc? Assuming this is a copper PBX. have you tried to reset any station modules power where those phones plug into?

It is dropping the call during different times. It may ring once, it may drop right before voice mail, or during voice mail. It seems if they answer the phone, it does not drop.

      Wow, throwback.  VERY VERY briefly - but realised that it wasn't the language I needed for the tasks I was taking on.
    • Apple and Tesla trade secrets reportedly exposed following a Tata Electronics cyberattack

      Apple and Tesla trade secrets reportedly exposed following a Tata Electronics cyberattack by Hamid Ganji Image via Depositphotos.com Tata Electronics has confirmed that it detected a cybersecurity incident in some of its systems. The Indian company is a manufacturing partner of both Apple and Tesla, and the incident may have exposed some trade secrets belonging to the two American companies. The World Leaks ransomware group is said to be behind the attack, and it has reportedly posted up to 200,000 files on the dark web, including component designs and specification documents related to Apple and Tesla products. Tata Electronics told Reuters that its response protocols were deployed immediately and that the “incident has had no impact on our operations across businesses, which remain unaffected.” The ransomware group reportedly sent a ransom demand to Tata Electronics, while Apple has launched an investigation into the incident. World Leaks claims it stole more than 200,000 files totaling over 630GB from Tata Electronics. Some database files on the ransomware group’s website are titled "com.apple.factorydata," which could refer to Apple’s iPhone production operations in India. Moreover, some documents reportedly contain material specifications and quality inspection standards for iPhone circuit board components. However, Apple is not the only affected company. A folder found in the World Leaks database is titled "NV36 Chargeport Controller - North America," which may refer to Tesla Model Y components. Additionally, other files in the database reportedly contain drawings related to Tesla’s Project Highland, the internal codename for the EV maker’s updated Model 3 sedan. To support the authenticity of the stolen files, World Leaks has published documents containing footers that read: "This document contains proprietary and confidential information of Apple Inc." and "information contained herein is deemed confidential, proprietary, and a trade secret of Tesla Inc." Cybersecurity researcher Rajshekhar Rajaharia told Reuters that the database also contains emails, event logs spanning several years, and passport copies of employees, including foreign nationals. Both Tesla and Apple have declined to comment on the scale of the incident.

      If they don't sell enough of the 1st gen then there won't be a 2nd gen

      Epic fail, should've added an eSata port on the back, also if the memory/NVME are soldered then they're hardly gonna sell any, first thing most people do with their Steamdeck is, or used to be, replacing the NVME with a 2TB one. At that price they should, possibly for the first time, offer an installments option, say 24 months, they may sell a lot if they do. I'm sure they would have no shortage of credit companies willing to partner.
