Telecommunications

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.

Need 2-line analog phones (not VOIP).  Can't seem to find anything reasonably priced for my client.  Their needs are pretty simple:

1.  Telephones (quantity 4) for two-line analog.
2. Must be able to indicate when a call was missed or message was left, by way of an LED on the phone.
3. Must be able to page the other phones (hands free) by pressing a page button.
4. (optional) Intercom capability.

They currently have 2 of the Cortelco 7-series 2740 phones. These have been replaced by the 2750, and they're over $200 each and take 3 weeks to ship.

Anyone have a better idea for 2-line phones?

Thanks.

Meet the Family that is Made for Collaboration

The TeamConnect Family product group as part of the Sennheiser for Business Portfolio comprising high-quality, technically well-conceived meeting solutions for business communication – designed for any meeting room and any meeting situation.

We supply a software application that is run on Remote Desktop servers (each client has their own Virtual Server).  One of the areas I am currently researching is to provide the ability for users to click on a "Call" button in our application, and dial the number (whilst connected to the RDP).  I have found a couple of solutions that will allow me to press the "Call" button, which will then dial the recipient's number (along with the user making the call), which in theory, should be ok - but I am yet to test it and am interested in all options.

For me, the perfect solution would be for users to be able to plug in a headset on their local laptop, run the application on the Remote Desktop and call - without impacting server performance in any way.  Or, if they have a phone system already in place - somehow dial through that.

Any pointers, products, suggestions - would be massively appreciated.

Do the Comcast Panasonic KX-TPA65 VOIP phones also have a network jack for plugging in a PC (in addition to plugging the phone into the network)?

If your answer is factory reset, please skip this question.

User reported a problem for iPhone 7.

On iOS 11.0.2, outgoing phone call  can be made but no incoming phone call could be made.

On iOS 11.0.3, the situation is reverse. No outgoing phone call could be made whereas sometimes incoming phone calls can be made.

However, if the user dials a USSD code which is carrier-specific, it will be OK to dial an outgoing call for once.

Already contacted the carrier and the SIM card is fine on another Android phone or iPhone.

How to fix without factory reset?

Phone call is a basic feature of a smartphone and I have not encountered similar problem in any Android phones.

I need some insights on how to start a call Center for a medical office. The office averages about 350 inbound phone calls per day and 200 outbound calls daily. Any suggestions as of best applications, service providers to use for this project would be greatly appreciated.

This phone will be exclusively used in Vietnam, 5% Cambodia, 5% Thailand.

Desired specs:
2G or more likely 3G, dual slot, camera, internet capable, touch screen.
Apple and Samsung won't work as they are too expensive.

As far as data for internet I do not know how many GB they would desire (or really need) and I can not pry to much as far as what they would want. The gift is to be a phone far better than the one they have (previous question on Nokia 150).
-------------------------
CDMA is not used outside of North America, so you will not get any coverage at all. Your CDMA phone will useless in Vietnam or prettywell anywhere outside of the USA and Canada (and even there CDMA is a dying standard). You will need a GSM phone and one that operates on non-North American frequencies; i.e. a quad-band phone.

I thought I had found an optimal solution in Possio Greta:

https://gizmodo.com/235790/possio-greta-combination-printer-scanner-fax-and-cellphone

But I talked to the head office in Sweden, and it turned out that it doesn't work everywhere in the world. I can't remember the details now, but I had a lengthy discussion about it, and it's of quite limited use for me when I travel between different parts of the world and different countries.

Otherwise, is there any alternative to smartphone and internet, such as a small portable fax machine or any other device or other type of communication (analogue instead of digital etc.)? Telex, satellite, short-wave radio, SIP for fax etc.?

We have KX-NT700 model, and was working fine with our Panasonic PABX, until we check it today.

The dial tone is missing when we press speaker phone, hence not able to call.

The basic settings are intact as i compared with Phone Manual, such as :
IP + TEL.

We are trying it through the telephone extension line (Ext: 222) , while this line is being used with KX T7665 without any issue.

For your knowledge, this phone had an extension of 300 while it was working fine before.

Please suggest if there is any configuration issue in the phone or this is a mechanical fault in it ?

Thanks in advance.

I'm confused with the above.  Is there just one type of Samsung Note 8 i.e. are they all dual sim compatible?  because the above web site does not explain the different between the two options and on Amazon people are selling the dual sim versions for over GBP 1000 where is the single sim is GBP 800.

I am looking for a free cloud-based call center software such as Fenero. There is nothing wrong with Fenero except that they don't provide any support at all getting started unless you sign up to pay significantly and monthly.

In their comparison at the bottom of this page, http://www.fenero.com/, they mention Five9 and InContact as being more costly solutions. SalesForce is very costly and is out of the question.

We will be making outbound calls and doing emails.

Free or pay-per-call or pay-per-support incident would be a better model getting started than would a monthly option.

Assistance in finding a better solution for this would be greatly appreciated.

SIPp is a free SIP traffic generating tool for Linux.
http://sipp.sourceforge.net/

SIPp user manual says you can install SIPp under CYGWIN on windows. However I am not experienced  with compiling applications to run under Linux and need help getting SIPp up and running under CYGWIN on a windows10 machine.

I have successfully installed CGYWIN and included the following packages (all successfully)
gcc-core
gcc-g++
gcc
libncurses
make

After the CGYWIN install, I put C:/cygwin64/bin in the win10 systems’ environment variable PATH – so far all ok and CGYWIN seems to be working fine.

In addition, the SIPp install instructions state:

Warning
SIPp compiles under CYGWIN on Windows, provided that you installed IPv6 extension for CYGWIN (http://win6.jp/Cygwin/), as well as libncurses and (optionally OpenSSL and WinPcap). SCTP is not currently supported.


QUESTION 1 -  Do you know what this is???    IPv6 extension for CYGWIN http://win6.jp/Cygwin/ 
is it a CYGWIN package, and entire install version??
What/how do I need to do to check/install?

QUESTION 2 – Nothing happens when I try to run “autoreconf -ivf” ...but this might have to do with Question 1 not being addressed yet.

 /cygdrive/c/Backup/tools/SIPp/3.3
$ autoreconf -ivf

We have two different telecoms setup here. Anyhow, I want to move the Xerox machine with a dedicated line to another room. the dedicated fax line is using a RJ11 and ther eis also a RJ45 data port being used. The other room is setup for RJ45.

My issue is moving the dedicated Fax line. The line comes to the printer with no moving room. I'll either leave the box in place and use a longer Ethernet cable and wire it for RJ11 and move it to the other room. I haven't climbed into the ceiling yet to see if there is extra wire but I have to move it over 50 feet. I was thinking to leave the box in place and put a cable into the box and then feed it back up to the ceiling and run it across to the other room I need to put the Xerox in.

Does anyone have an easier way of doing this or any other ideas? I hope this makes sense...

Any questions please let me know.  I can also attach pictures...

[Video] Oticon Case Study

Open office environments can create the dynamics for innovation, but they also bring some challenges. With over 1,000 employees in an open office, Oticon needed a solution that would preserve the environment while mitigating disruptive background noises.

Watch how they did it.

Hey all, i have an issue that external calls has noise, delayed audio from the external side. Internal calls are fine.
We recently changed from the Telstra supplied modem to a Draytek Modem. All ports have been opened up the same as they were on the Telstra one, all lines and SIP registered straight away, however i have not been able to resolve the noise.
As Draytek have alot more advanced firewall settings, QOS, I'm not sure what feature / settings i need to change to test.
We are running freepbx 2.11.

Thanks

Hello Experts,

I am in need of options to connect an analog phone to an old, Nortel PBX that is in another building with no physical, wired connection between the two buildings.  There IS network connectivity between the two buildings, and I've been told by our phone support \ vendor that there are devices available that would connect to the analog port on the PBX on one side, and to the phone itself on the other side, and then both devices would connect to the LAN to provide connectivity between the PBX and the phone.  Our vendor, however, has very little info on these.  I am writing to see if anyone here has any familiarity with this concept, and if so, can provide any recommendations or guidance on makes \ models they have used successfully in the past?

Thanks in advance for any help that can be offered,

Russ

I have an old CallManager (4.3). it works great and no one wants to upgrade it. I have several small offices and individuals working from home offices and in order to have working phones in their locations I have to do site-site VPN's to each location.
Is there way to create some port forwarding and avoid VPN? Which ports? Any downsides?
The firewall is Cisco ASA5510 and they have Cisco 7941 and 7970 phones if that matters.
Thanks!

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
