Hello, I'm curious, hence I ask you; Is there such a "recent college engineer", either software or hardware, or one that studied both, who would meet all of these requirements:
embedded Linux based data telecommunications system/ VoIP/SIP
satellite network application and
embedded software/ Firmware/embedded systems
automation scripting
Python
Java
Linux operating system/Linux Network expertise
Unix shell scripting
WEB GUI test automation
DO-178B experience
Satellite communication experience
Telecommunication experience/PBX switching systems

Any comments?
Do companies expect to find an "expert" engineer with all this knowledge?
thanks

Portable, direct connect server access
Portable, direct connect server access

The ATEN CV211 connects a laptop directly to any server allowing you instant access to perform data maintenance and local operations, for quick troubleshooting, updating, service and repair.

I used this Note 5 for 2+ years with a great experience.  Great phone - large bright screen 5.7" 2560x1440 pixels, fast 4GB RAM and 32GB Storage, 16mp camera.   All good except.. battery life is terrible.  Time for an upgrade.  
Should I stick with Samsung and go with Note 8 or what would be other recommendations?  

Thanks in advance.

I just signed out of a Google Voice account on my Samsung Galaxy S8 phone.

I have logged in with another Google Voice account which is the one I want to have associated with my cell phone.

The problem is that when I make phone calls using my Samsung Galaxy S8 phone the caller ID for the most recent Google Voice account (510-xxx-xxxx) displays instead of the caller ID for the other Google voice account I have switched back to (415-xxx-xxxx).

I also remember that when I have set up Google Voice numbers in the past that these Google Voice numbers have given me the option to fully integrate Google Voice with my Sprint PCS phone (which is what I want to do now). However I am not given this option at this time.

What do I need to do to fix this issue so that the phone number associated with my 415 area code Google voice number will display whenever I make phone calls?

I own an Avaya ACS509 R7 BUSINESS PHONE SYSTEM NAMED PARTNER. One of the extensions,the main programming extension number 10 is not functioning 100%.There is an illuminated button that can be designated as DND (Do Not Disturb). The button does make a click in the receiver but does not turn on the DND feature nor does the led come on. I have tried several identical phones on that  line and none of them work. All of them work different extensions. So, I must assume it is the main controller board. I am an Electronic Technician and probably can repair it IF I could locate a complete schematic diagram along with pcb board layout pictorials and part numbers/values. I do NOT need the programming manual or user's manual. ONLY a technical repair manual. They must exist somewhere since there are several locations that will repair this motherboard. I would really appreciate it if any Expert could direct me to a pdf or similar for this unit. It is also referred to as an ACS-R7 unit. Anyone assisting me will be the recipient of 735 virtual Kudos!

NOTE: This is NOT a voip system. Just a regular 20 extension phone system.

Hello everybody,
I am a junior telecom consultant and am working on a ToIP migration project.
My client has some specific needs to be satisfied in his new ToIP network and i need your help as soon as possible.
in fact i have 2 questions :
             * Can we chain 2 IP phones on the same PoE switch port knowing that the 2nd phone will be connected to an external power
                supply  ?
             * What are the potential risks or the disadvantages of chaining the PC behind the IP phone ?

It will be helpful also if you can share with me a document describing this topic.
Thanks in advance, i'll be grateful.

Is it possible to have a call attendant on Google voice , just even greeting or music?

My company wants to compare pricing on hiring a full time switchboard operator versus outsourcing to an answering service.  We have one published number for the company even though all departments have a DID line.  The company is against automated attendant so the current choices are 24/7 answering service versus hiring an operator.  The idea is that the company main number would be forwarded to the answering service who would take the call and answer as "companyname."  They would then transfer the call to a DID number at our company to complete the call.  Obviously, the answering service would have a directory of DID numbers to forward to.

I am looking for some answering services that people have tried and have been happy with.  I just want to get an idea on pricing since we'd be comparing it to hiring a full time employee.

Please provide me with a URL address of the Sprint PCS add a phone program.

I know several users who all currently have a single Sprint PCS cell phone and are interested in finding the details of how they can add a second phone to their Spring PCS account using the current Sprint PCS promotion that we have heard is going on until the end of June of 2017.

Need to run direct burial CAT5E with telephone signal lines and intend to terminate with RJ11 plugs.
I find that the wire insulation diameter is a bit large to assemble the cable end into the plug.  
I suppose that I could terminate the CAT5E cable with a modular jack and then use a telephone cord (RJ11-RJ-11) from there.
Yet, the same issue isn't anticipated on RJ45 plugs.
Is there a wire diameter (including insulation) specification for RJ11 that's smaller than for RJ45?

Hello all,

I have some Win 2012 3cx v15 phone systems and was having trouble with apple push notifications for calls to remote devices.  I've determined it to be a TLS issue.  I had used IIS Crypto to remove the less secure SSL 3.0, TLS 1.0 and 1.1, leaving just TLS 1.2 and more secure ciphers.  This breaks apple push notifications from the 3cx server/software.  I put back TLS 1.1, no luck.  Put back TLS 1.0, now push notifications work.  I find it odd that I should still need 1.0 enabled on the server.  

Is apple push still using that protocol and not 1.1 or 1.2, or might there be something else going on here.

I'm by no means familiar with protocols/ciphers, just determined what fixes the problem.

Hello

I learning up about Skype Enterprise Voice and it's potential for mobile.

Right now, we use Skype for Skype-to-skype calls. I'm wondering if this can be integrated with the telephone line in the office.  And then, if we can deploy a Skype mobile client to user's personal devices that has their office number....this way, we can :

1. A user never has to give out their personal mobile number, only their office number which will now ring on their personal phone

2. A user can make voice calls, either internally or externally, using this Skype client and reduce cost to them since it presumably uses the corporate network where possible, e.g. for international calls.

Some questions.

1. Is Enterprise Voice the term for the integration of Skype with the phone network

2. When we refer to the Phone Network, do we mean PSTN?

3. Is there a way for an enterprise Skype mobile client to have an external dialler feature so the user can phone anyone, either internal or external?

4. Are there potential cost benefits of this Skype client connecting to the corporate network

5. Is it possible for Skype mobile to have the user's office desk number so that it provides the fixed mobile convergence i talked about? Or does it need a separate number?

  • Have a deployment of 3 servers using dns loadbalancing.
  • we have a trunk setup via an sbc.
  • users have deskphones (CX600)


both inbound and outbound calls work as expected.


however, when a call is placed on hold after 30 seconds the call drops.

the same thing occurs when a call is parked..also after 30 seconds the call drops.



i should mention MOH IS SETUP in this deployment, however when an external call is parked there is just a beep sound.

when a call is parked between users MOH does work and the call does not get dropped.

refer and bypass are set to false on the trunk as well.  Trunk settings



in the snooper log i see references to "this call leg has been replaced"  in the same message as the BYE:
ms-diagnostics-public: 10026;reason="This call leg has been replaced";component="MediationServer"

the trace from the sbc shows that the mediation server is dropping the call so i haven't mentioned that here.

have the snooper trace if needed.


any suggestions appreciated.

Hello Experts,

I have ARM board linux and I established offline access point (using USB dongle) to connect my laptop with ARM board. The IP is 192.168.1.0/24
On the same ARM board I have mobile 3G connection to the internet (SIM card with dynamic IP). My purpose is to allow my laptop to connect to the internet via 3G.
What should I do? Do I need to set some routing or gateway?

Thank you.

With the ATEN CE624, you can now enjoy a high-quality visual experience powered by HDBaseT technology and the convenience of a single Cat6 cable to transmit uncompressed video with zero latency and multi-streaming for dual-view applications where remote access is required.

Hello

I quite often make visits to buildings where there is no Wi-Fi I can utilise. In the meetings, I'd like to be able to use my laptop and have it connected to my work VDI.

I have a personal MacBook Air with a USB port. What is the best solution to have in order to connect to a 3G/4G connection via Cell to provide me internet access at an efficient price? Since I am actually connecting to my work VDI, this will only be light browsing traffic, no downloads or anything.

Thanks in advance.

Hello,

Can anyone point me in the right direction? There are a few google hits for this problem, so it seems like a known issue.

///////Summary: On outbound calls, we are sending out caller ID, and it is showing as "restricted" on HD enabled mobile phones only. Older mobile phones and land lines display our caller ID correctly. The telco PSTN providers have all pointed to our call manager as not providing the correct 1TU-T E.164 standard. This is occurring on all 5 MGCP gateway PRI's across multiple local PSTN providers.


///////System Parameters
We have 2 call managers in our HA cluster, 1 publisher, 1 subscriber.
Cisco Unified CM Administration

System version: 10.0.1.12900-2

VMware Installation: 2 vCPU Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz, disk 1: 80Gbytes, 4096Mbytes RAM, Partitions aligned


///////Troubleshooting Steps
Here is the support forum posting of the same issue, I have performed the changes advised in this posting with no success:
https://supportforums.cisco.com/discussion/12746556/debug-caller-id

1) Under Service Parameters - Clusterwide Parameters - Calling Party Number Screening Indicator

Set this value to Callmanager Provides Calling Number (No success)


2) I have performed the changed to Call routing information - Outbound calls, tested with Calling Party IE type as both "national/ISDN", Calling Numbering plan "ISDN". No success.

Here are our test call DNs appearing in the debug isdnq931:

Hi All,

Can anyone here please suggest how to do the 24x7 Skype conference call between two remote office location?

At the moment I'm using Free Skype to show the two meeting room from different cities so that they can just walk in and then arrange the time to discuss without having to contact IT to dial in the other meeting room PC.

But the problem with Free Skype is that you cannot leave the connection running for 24x7 or schedule it so that after the PC reboot, it automatically dials the other meeting room.

My requirements:
24x7 audio & video call between two computer with Webcam in two different cities.
automatically re-establish the connection if it is disconnected.

Does Skype For Business can do this or even the Free Skype can be scripted?

212 in new york city
310 in los angeles

those two areas codes on a cell phone are a status symbol

But I am from a technical background and I know that older phone numbers have longer history so more likely to get spam

Does a phone number ever get less spam

Are you advising clients to change their number to the new area code (that is not a status symbol)
