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.

Lately, our staff complain about receiving multiple spam calls daily from what appear to be 'spoofed' local numbers. It started about two weeks ago and it looks like somehow direct numbers of staff got in the hands of wrong people.

Is there something that can be done about this?

Thank you!

Ok, this is the last part to getting our site paging worked out.
I need to know how I can get our ShoreTel phones speakerphones to work with Valcom speakers when a page is sent out.
We have a ShoreTel system 14.2 director and Valcom v-2003A paging controller.  We need our system to page all phones and all Valcom speakers at the same time.
Can this be accomplished?
If this scenario cannot be accomplished with our current equipment then what would I need to replace/upgrade?
Hi all, we need to have call recording for our VOIP system, does any know of a 3rd party vendor who offers this? Our current vendor and we are not switching anytime soon.
i am wondering if anyone has any experience in telephone  call accounting software.  i have a client who uses a piece of software called phonecontrol (
i am wondering if there are other options out there.  they want to be able to see call costs for extensions on their samsung phone system so they can on charge their tennants.  

the phone control version they have can no longer be activated after  we had to reinstall their windows OS.  and the software support has not been helpful.  so looking for alternatives.
android 7
automatic call recorder
free version
app version 5.42.1

recordings were good then I noticed last recording was at a low volume
Maybe in a version upgrade
volume is lower which is very difficult to hear
If I pay for paid version, do you think this will fix.
We have been using Skype for Business (formerly Lync) for IM and video conferencing but are thinking about using Skype PSTN as a replacement for our current PBX.

We are in the process of organising a trial for some users to pilot Skype for Business as their only phone option.

One of the things we need to do is gather some data once their trial has finished and I am looking for help identifying test criteria for the new system.

If you have any thoughts about the sort of questions we should be asking users to assess the suitability of Skype for Business, then please let me know.

Thoughts so far:-

Which microphone device do you normally use for S4B phone calls?
Which amplification device do you normally use for S4B phone calls?
Frequency of use
In a typical day, how likely are you to make a phonecall using S4B
In a typical day, how likely are you to receive a phonecall using S4B
Sound Quality
How does the sound quality compare to landline
How does it compare to mobile

Any questions / comments appreciated.

Hi, we have a data network here with Cisco switches that we manage. Now, there is a also a VOIP vendor who his own switches in our network. (He didnt want to use ours and VLAN everything).

Both the networks are on different subnets. Now, we noticed all of a sudden PC's started getting IP's from the phone subnet...and it's wreaking havoc internally. I tried to manually trace all 200+ cables in the office to see if someone plugged a phone device into the data network, but no luck..

How else can i troubleshoot this from say a switch level?
help with setting up VLAN on a few switches for phone and data equipment.

i have a series of managed switches that are uplinked together.  I would like to set up a VLAN 100 for a dedicated router that is on port 48 of one switch. This router will listen to requests from phones that are plugged into any other random ports on the switch.  This switch is a ubiquiti unit that allows me to set port 48 to listen to vlan 100 traffic only.

The phones are set to 802.1Q with a vlan of 100.  there are other computers and servers on the switch that are on a 192.168.0.x subnet.  The server is handing out DHCP as well as the router on port 48.  The idea is to isolate the traffic for the phones to ONLY communicate with the DHCP server on port 48.  

Right now, this setting is working. However my question to you, is since the phones are all plugged into random ports 1-47 and set to vlan100  and these ports are set to listen to both default lan traffic as well as i simply congesting the switch with added default and vlan traffic vs setting the actual ports that the phones are plugged into to ONLY vlan 100?

Also, if i plug in another switch,, do i need to set the uplink from one switch to another switch with a vlan100 for them to comminicate or will they pass the phones traffic that is tagged 802.1Q VLAN 100 traffic to the other where the port 48 will ultimately listen and grab it? Thank you!

Polycom Soundstation 6000 not saving the Provisioning user information.  It saves the URL, but when you try to save the username and password, it "says" saved, but when you reboot or refresh the page, the credentials revert back tot the default one.  I also tried to enter it through the display (not the web UI) and same results.

I also tried to update the firmware, tried almost all of them and still same results.  Anyone have any other ideas?
A customer has recently had new phones installed that connect to a cloud based PBX.  They have a Draytek 2860 router.

They have sent me a document with the required entries in yellow (attached).

I presume they are asking that the firewall be opened up for those specific ports to the hostnames/ip addresses provided.

Can someone explain how I do this on th Draytek router

Currently we having issue to make outbound and inbound call.

We suspect firewall is blocking, how to resolve the issue in Cisco ip phones.
I recently moved a small Call Center from one location to another. They contacted me late in the game to help them get a new call center setup with very little time. This left me with Comcast as the only ISP to choose from that could install services within their timetable. We decided to go with their new Gigabit package, which includes their new Gb modem. The client also chose to go with Jive for their PBX needs and subsequently ordered 20 Yealink T40P IP phones. Let the issues begin...

Comcast's modem would partially default to factory settings once a week. When I say partial, I mean things such as factory internal Gateway IP and Subnet revert back; passwords are set to default, yet the SSID's are still what we created. Comcast claims that they can ping the modem but when I test connectivity inside the modem to the internet I get 0/4 packets received. This test was run by the modem internal troubleshooting software. The Uptime clock inside the modem says 17,500+ days, which is not possible since we have reset the modem within the last 24 hours and we have only had the service for three weeks. We have factory reset the modem, replaced it with a new one, and we are still having the Yealink phones not obtain an IP address, or they have an IP address but say "No Service", even after they have previously worked. Phones continue to drop off of the network in that manner, and PC's that are using pass-through are losing connectivity as well. No matter how many factory resets on …
