Robo Calls


“Robo Calls are the most significant current threat to humanity.”

This may not be a completely true statement, but some days you may agree. 
According to the FTC, consumers get “tens-of-billions” of illegal calls annually.
This can lead to significant distractions for your employees who receive inbound calls.  While the FTC and Department of Justice are ramping up their efforts to prosecute and fine abusers, this has little impact on calls from outside the USA.  Both the mobile providers and the enterprise SIP carriers have begun to take action to combat this epidemic with technology-based solutions. 
The root of the problem is these robocallers often alter their Caller-ID at random in order to deceive you into answering.  Many times they will use a number selected from among your neighbors, increasing the likelihood you will answer the call.  Technologies such as STIR/SHAKEN will ultimately create a global network where providers authenticate the source and Caller-ID of the calling party before you ultimately receive the call.  Until these technologies are more broadly implemented, there are some steps you can take to reduce your annoyance and the number of robocalls you receive.

Within your Enterprise UC system:

Block the Caller-ID of repeat offenders
While many of our clients have taken steps to log and block calls using the Caller-ID of the caller, this can many times block valid calls from your community as well.   Ask our team how you can utilize “Call Routing” rules in your client software, or the “Mitel Nuisance Call Handler” to block incoming calls based on Caller-ID.

Configure a “Transfer to Message” button:
This will give your users the option to easily transfer a robocaller to a message, and give them the option to press 1 to leave a voicemail.  (Using this option will also allow your team to periodically run reports looking for repeat calls from the same numbers which were identified as a robocaller.)

From your mobile phone:
1. Don’t answer calls from unknown or restricted numbers
The majority of robocalls come from randomly-chosen numbers, many times from your own area-code.  Sending these calls to voicemail allows you to screen these calls.
2. Join the National Do Not Call Registry
In theory, signing up for the Do Not Call Registry should protect you from telemarketers and robocalls. Adding your number to this free government database can somewhat reduce marketing calls to your number.  Illegitimate or International robocallers will still ignore this restriction.  http://www.donotcall.gov
3. Use the blocking services provided by your carrier
While telephone carriers have generally treated telemarketers and robocallers with kid gloves, many carriers provide tools that can help you block known fraud and spam. Each carrier calls this something different, and some services cost a little extra, but if you’re serious about ending robocalls, this is a handy defense. AT&T’s “Call Protect,” Verizon’s “Call Filter Free” and Sprint’s “Premium Caller ID” are all examples of anti-spam services.
4. Block individual phone numbers
Most smartphones make it easy to block a number. Once that call comes in, you can press a button that says “Block this Caller” (iPhone) or “Block/Report Spam” (Android). You can go through your call log and block the number retroactively as well or unblock it if you realize you actually want to receive calls from that number. You can also set “Do Not Disturb” on both iPhone and Android phones, which will prevent people from calling you at certain times.
5. Use an app
There are many well-rated mobile applications which utilize both Artificial Intelligence and an ever-increasing database of offenders to block calls to your mobile device. While looking for apps, pay attention to the cost and the reviews to get the best solution.

DD-WRT to xfinitywifi

This weekend I setup my Mother-in-Law's apartment.  She needed Internet, so I cobbled together a repeater to piggyback on the very strong "xfinitywifi" signal in the building.  As an xfinity subscriber myself, I am able to utilize this service with a valid login.

Here are the notes I followed, and some of my results:

First I had to change the MAC address on my MacOS to match the MAC of the WiFi device I was planning to use to connect:

Here are the directions I ended up following to configure the DDWRT to actually connect to the xfinitywifi AP and begin providing service to the LAN ports:

ShoreTel - Fix DTAS disconnect errors between servers

In some cases, we have seen DTAS disconnect issues between ShoreTel servers.   

Making a change to the system to force a socket reset could solve this problem: 
1) Navigate to HKLM\Shoreline Teleworks\Telephony Management Server\Settings
2) Create a DWORD value called ForceAsyncSocketReset
3) Set the value to 1
4) Restart the DTAS service.

This change will need to be made on all servers and has fixed the problem in many cases.
