Hi

We are currently evaluating option to move our voice to hosted.  We are in the process of two part project for this.  1st is migrating from VPN to MPLS.  The 2nd is to move from PBX/SIP to hosted.

Currently using Shortel and planning on gamma.

Anyone gone this route and suggest any options or caveats?

Thanks

Hi All, I am attempting to configure an AAPT IP based trunk in 3CX via a dedicated TPG SIP service, and am struggling to get it working.

What I really am after is examples of working AAPT trunk configurations that I can compare my set up to.

If anyone out there could provide some examples of correct trunk configuration, I would be extremely grateful.

Wireshark shows OPTIONS messages successfully hitting the phone system from TPG SIP server, and 200 OKAY messages being sent to TPG SIP server.

EDIT:

 - 3CX on premise
 - Wireshark shows OPTIONS being received and 200 OKAY being sent to/from TPG SIP IP
 - Dual WAN connection with dedicated SIP service on WAN2
 - NAT on WAN2 to local IP of 3CX
 - Static routes are configured to route required SIP traffic in/out via either WAN1 or WAN2 depending on what port is required

Kind regards,

Nick

Hey guys,

I’ve recently started a new role and I’ve noticed that the guy before me has configured his guest WiFi to use the internal DNS for name resolution....traditionally, the approach I’ve always taken is to direct all guest access off the LAN and to use the DNS of our ISP.  Surely this is a security risk? The guys here say it was done to control/manipulate and secure DNS - but I’m not seeing their point.  Can anyone shed some light?

Cheers

Dear Experts, I have a question related to telephony service. We are using IP PBX Grandstream UCM6510 with SIP trunking from The Provider.

So as my understanding, for example if our number is +AA 710xxxxx; I create a conference room in UCM6510 at ext 8888; then when customers want to join a conference room with us, they will call to +AA 710xxxxx, press 8888. Am I right? (AA is my country code)

But the Boss now have some customers in USA, UK,... and he wants his customers will call to USA, UK numbers, (for example: +1xxxxxxxxx; +44yyyyyyyy) respectively instead of our number (+AA 710xxxxx)  to join our conference room.

Is this feasible? Can you please suggest the solution? Many thanks!

In Skype for Business Server 2015, Is there a way to disable clients from retrieving location information from the LIS/Secondary LIS every time the client registers with the server? I want to prevent the client from performing a HELD request to get location information when it first registers to the server. Is this possible with the on-prem server?

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?

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 (phonecontrol.com).
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.

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:-

Equipment
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.

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 vlan100...am 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
