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.

I have a question about whitepages and most public address services.  Are most of the numbers that are found in these databases mainly landlines or are there cell phones on these listings.  To my understanding, cell phones are private but most people don't use a landline nowadays.  When whitepages, superpages, etc, does their listing what types of phone numbers are they pulling from?
hi Techs. We just switched from Verizon to Comcast Mobile. a very strange thing happened on my wife's phone right when we switch. she received a text from an unknown contact regarding my phone number. I'd like to ask if it's possible if Verizon was somehow hacked into my phone.

On another note.... our phones are running so much better than Comcast!  no glitches and weight faster.....
Can guide me step by step how to set up zoom (or any other free video
conferencing facility) that I can connect my Win10 laptop (it's Chrome &
IE has a proxy setting which only permits me to browse Intranets only)
with external party (auditor actually)?    Heard that zoom will time out
(I don't mind reconnecting) after 40mins but my video conf session is
2 hrs.

I do have portable browsers (eg: Maxthon & Falkon) that enables me
to browse Internet though so this one can be used for zoom or any
other free facility if needed.

Meeting room & my laptop use HDMI.
I'm setting up a 3CX PBX on Amazon Lightsail, and I'm having trouble with setting up conference calling that will allow external participants to dial in (like FreeConferenceCall.com, or other similar services).

I have my inbound and outbound calls working, so I assume my basic setup is okay. I have one number I purchased from Skyetel (the VOIP provider I'm using), and I have another number that's being ported in from Skype (not yet active on Skyetel).

However, I'm not sure how to properly setup conference calling on 3CX. I have a single extension (00), and I have all of my trunks (inbound and outbound) set with the "Trunk" value of *1949 (the last 4 digits of the number I purchased from Skyetel).

In Settings >> General >> Conference, I set my Conference Extension to 00 (the only one I have), and I've set my External Number to the number I purchased from Skyetel (the one ending in 1949).

Are there other settings I need to host conference calls?
Now that Skype no longer allows a customized voicemail greeting, I'm looking for an alternative.

I have a Skype Number that I'll port over to the new system, so it needs to accept incoming calls on that number. Other than that all I really care about is voicemail. Skype cost me about $100 a year for the number + my plan, and I'd sure like to stick around that price range.

Any ideas?
Hi Experts

Could you point how to automatize SMS generation by using data from a SGBD?

It is a relativetely simple to generate emails on that context  but SMS is a telecom  feature.

Thanks in advance
Hi experts,

We were using a server without VMs with a Mainpine Faxboard. This more than handled out incoming and outgoing faxes. We moved to Windows Server 2016 Standard with Hyper-V and two VMs. Configuration of a fax board is not practical.

I have been using a Canon MFC as my fax server. It works OK, but first, it just isn't as efficient as a high-end fax server; and it only has one line. I know that other MFCs like the ImageRunner come with two lines, but then I am paying for yet another fax machine.

I have been researching standalone fax server appliances, and I have only come up with one brand: https://www.cimfax.com/products_T5.asp. The Cimfax Professional two-line fax server is the lowest in its lineup that has two lines and a 33.6 fax modem. I have found it for $600+, although it is listed on their site at a little bit more.

My question to the experts is do you have any other recommendations for a fax appliance? And, are you familiar with the Cimfax line of fax servers?

Thank you.


PS I do have two separate fax lines, and I am not interested in any cloud or internet faxing solutions.
The phone is Polycom VVX 350, provisioned by RingCentral.

Is it possible to somehow program the Polycom phone to produce a distinctive ring if a specific number calls.  A mobile phone can do this.  I wondered if there is any way that I can get this feature? If not Polycom, is there another brand of VOIP desk phone that has this ability?

The user has moved into a new apartment.  They brought their Panasonic wireless home phone system, with a base station and two satellite phones with them.  

They would like to just give everybody they know only their cell phone number.  They need an adapter that would transfer all the cell phone calls to their Panasonic system.  This way they have the convenience of the Panasonic stations, and don't have to carry around a cell phone all day.

What is a good unit that will do this?

The user lives in an apartment complex that provides phone service as part of the rent. They were able to connect their Panasonic wireless home phone with 3 stations to this system.

However, even though the wireless phone receives calls, the caller ID isn't working.  Most inbound calls show the ID as DID/DOD.  Outbound calls show the town or just the phone number.  I called my iPhone, and my iPhone recognized the number as being on my contact list, and thus showed the name.

In addition, the answering machine built into the main station usually doesn't pick up.  Management said that an answering machine should work.  The Panasonic HAS an answering machine.

Is there anything we can do to get the caller ID and answering machine portion of the Panasonic phone working?

Say, the following device :  D-Link 3G FLLA Wi-Fi Model DWR-720/PW   takes a SIM card and allows one to mkake telephone calls from the built-in handset. It also offers wifi to the user. We are loking for a device with similar functionality as described, except that it does not need a handset but rather a FXO Port allowing one to connect in a regular POTS.
The important features are the Wifi for the end user and the ability to plug in a POTS. Cost is a factor and availability in South Africa is preferable. Kindly suggest devices ofering this functionality.
PS.  This device is being used as a replacemenent to a traditional analog telephone
Someone spoofing my number and calling another person with mortgage offerings and other services.  
The area codes and prefixes of my number and other recepient's number are always the same.  Last four digits are always different.  Both numbers are with AT&T carrier in US.

Anyone had experience how to deal with it?  
Any solution besides keep blocking them?  Can AT&T do something about it?
We have a yealink IP SIP phone that needs to connect from the outside.  We have set up the phone and tested it internally and it's good so we moved it externally.  

In the phone, we edited the account and put in the public IP of our router (a Sonicwall NSA4600) and waited for the phone to register.  It fails to register.

I've checked the ports and I DO have the right ports open on the Sonicwall but I've also read a lot of posts about people having trouble with SW and SIP phones.  So, after reading, I have made the changes suggested on the posts I've read and still no joy.  

I'm using https://www.yougetsignal.com/ to test 5060 and it reports that it's closed.

Does anyone have any insight into how to make the SW work well with the SIP phone?

PS:  An alternate port scanning tool tells me the port is filtered.  So, I'm looking up how to turn filtering off in the sonicwall for this service.

I'd like to know how to be able to subnet a PepLink Balance one router for less than 50 users. More concretely I'd like to have the IP phones on a  separate subnet. How can I go about that?
I have many voicemails that I transferred from my Android phone Samsung Galaxy Note 4 with a file extension .smil. that I can not listen to . Can you advise me on what to use in order to listen to them? Also, why does the voice mail gets recorded in this file extension not other ones like .avi or .mp3?  Thank you
I need to set up a switch to serve a VOIP phone system where clients connect to the network through the phone.
I've set up a ProSafe GS108v3 with 2 VLANs, VLAN 1 ports 2-8 untagged and VLAN 20 port 2-8 tagged (port 1 for connection to the firewall/router).
The Firewall/Router is set with QoS enabled

Is this sufficient/correct for use as intended, and is there anything else I should do to make this work correctly/optimally?

Thanks much.
Team ,
i have a design clarification ,where i have 2 - 3 sites, where sites are connected by MPLS link . They have video conferencing units installed but client is complaining of Jitter and  Latency on certain ocassions.

Now my question, in design perspective , should VC's be connected through ISDN than IP or is IP preferred with dedicated bandwidth for VC .

Hi, I am looking for remote software, preferably free, where I can have 2 people look at my display so I can give a presentation.

Thank you.
Hi, we have just had Avaya IP Office and Voicemail Pro installed on a Hyper-V Virtual Server (A Dell Poweredge R7040 with 32GB RAM Intel Xeon Silver 4109T 2Ghz (2 Processors). The Avaya virtual server has been running fine since Christmas but over Easter it crashed. The telecoms guys that support it say that for 1-100 users it should be at least a 4 Ghz Processor (we have 75 users) and 2-3 cores.

Now, I can shut it down tonight and give it an extra processor, but would we really need to upgrade the processors to faster ones? It's a fairly new server and I thought that the Xeon Silver 4109T although low Ghz are pretty good? Thanks for the help.
Is there a way to send text messages to a group without displaying the phone numbers / ID's of the members in the group thus achieving the same results as blind copying contacts on an email?  I use both android and ios phones.
This is (hopefully) a dirt-simple question for the Avaya IP Office gurus, but over 30 minutes of Google searching has yielded no results for me.

I have an existing Voicemail Pro module ("VM:Support") that works perfectly, and I know how to redirect external incoming calls to the module, but I need to create a single extension (x5555) that points directly to the module.  How is this done on an IP Office 500 / Voicemail Pro system?
Skype for business 2015 Yealink T48S | Trusted Certificate
I need assistance with phones we recently purchased, all T48S handsets with Skype for business firmware.
I have tried all 3 latest available firmware and stuck with this version as it offered a simpler login screen for users.
Phones register correctly for as long as the the trusted certificate is not present.
Periodically the handsets will populate with a CA certificate on line 1 even though everything is set to disabled below and then the users are unable to sign into the phones.


i did some googling and found this command but its only relevant for SKype for Business online

What is causing the phones to download the internal root domain CA certificate?
I have two iPhone XR’s I believe. One was stolen and it was my business line. Can I still forward calls from it to my personal phone without actually having phone in hand. I have sprint as carrier.
At a customer site we have a VoIP server running. The customer complains that the some voice conversations are not going well. Even with collegues next door.

The network guys have checked the network and told that there is no problem on the network. They tell that the voice server has not enough troughput or that the network card has an issue.

is there a software that i can install on the server to monitor the lan? i want to know what the max network troughput asked is. Not a measure like speedtest.net i want to know how much is asked when calling.

The server is windows based to i need a windows software.
Hi there,

I'm looking for a solution to make a 3 way voice call between 3 sites and hang 5 lines off each of those sites.

Two of the sites have 1 PSTN line only and one site has two PSTN lines, and each location would like 5 POTS/physical handsets to be able to use at any given time (not cell phones).

Site A - 1 PSTN
Site B - 1 PSTN
Site C - 2 PSTN

Each location also has IP connectivity between the 3 sites but it is setup like a WAN so is a closed network and there is no internet breakout. Therefore no hosted solutions can be used.

So far this says simple PaBX either traditional or IP based.

Each site can call out which is fine but there maybe times that each of the sites need to be on the same call together and have more than one handset from each site join a call.

The bit that I'm not clear on is if each of the sites want to have a 3 way call between them and have each of the 5 local lines connect into the same call. Would the easiest way to do this be simply have a PaBX system on each of the 3 sites and have two off the sites (A and B) with 1 PaBx dial in to the site with the 2 PSTN sites (Site C). Then have the PaBX on site C merge the calls?

This seems a little clunky, is there a better way to do this? Is there an VOIP/SIP solution that would work better?

Trying to keep this uncomplicated and keep margin for error to a minimum so simple PaBX solution was my initial thought. If this is the best solution, does any one have any …
