Project Atlas Aka Facebook Research Revocation By Apple Brings Hardships to Facebook
Fallback effects of yesterdays  "Project Atlas" by facebook seem to affect company's internal operations.
Facebook’s vice president of product engineering and security Pedro Canahuati issued an internal memo on Wednesday instructing employees to download public versions of the Menlo Park social networking giant’s iOS apps, following Apple’s decision to rescind Facebook’s enterprise developer program certificate.
According to a January 30th, 2019 Business Insider report, Facebook is aware of a “known issue with our internal, employee only, iOS apps. Apple has revoked our enterprise certificates, which means our internal, employee only iOS apps may not work,” reads an excerpt from Canahuati’s memo, obtained by Business Insider.
Not only does the Apple block affect internal versions of apps like Instagram, Facebook Messenger and the Facebook iOS app, Cupertino’s developer certificate revocation has also affected internal apps like ‘Mobile Home’ and ‘Ride.’ According to Business Insider, Mobile Home “provides employee information,” while Ride “deals with public transportation.” Canahuati’s memo also stated that Facebook is “working closely with Apple to reinstate our most critical internal apps immediately.” In the meantime, Business Insider reported that work inside Facebook has ground to a halt and employees are “pissed,” according to internal Facebook sources who spoke with the publication.

The Best Way To Setup A Publicly Accessible Asterisk PBX Or A Lesson About Network Security, VoIP And Linux.

 Publicly Accessible Asterisk PBX
I am a fan of Nerd Vittles, Ward Mundy's blog. I started posting about PIAF, PBX in a Flash days. Before being absent from this blog for a while, it was a weekly destination, if not daily. PIAF was a great solution for that time to run a VoIP Telecommunication server. Actually we had it as the office VoIP server for a while.

Now the telecommunication infrastructures, servers and platforms have changed since those times. Fittingly, Nerd Vittles has published a new Tutorial for a current use case. The new offering just not another VoIP Server setup for SIP communications, Security for opening the server to wide net is taken care of. The security comes in the way of time proven IPtables with additional security mechanisms now available with Fail2Ban, Asterisk, FreePBX®, and Travelin’ Man 3. What I found most interesting was the tutorial on DDOS protection using IPtables, a must read if you are even looking at a public facing server or device.
Another benefit of this setup is that IPtables and other methods are all open source GPL3 code which you are more than welcome to use or improve pursuant to the terms of the GPL3 license.

So what is the benefit of using server setup?
"Consider this. If everyone in the world had an accessible SIP address instead of a phone number, every call to every person in the world via the Internet would be free. That pretty much sums up why SIP URIs are important. The syntax for SIP URIs depends upon your platform. With Asterisk they look like this: SIP/ On SIP phones, SIP URIs look like this: Others use Assuming you have a reliable Internet connection, once you have “dialed” a SIP URI, the destination SIP device will ring just as if the called party had a POTS phone. Asterisk® processes SIP URIs in much the same way as calls originating from commercial trunk providers, but anonymous SIP calls are blocked."
