Frustrated at the cost of your phone calls? G7Eleven has the solution for you!

Voice over IP. The G7Eleven VoIP system allows a business to make and receive all telephone calls through an internet connection, removing the requirement for an expensive
fixed land line. “At G7eleven we are very busy converting hotels and other small to medium sized businesses from expensive fixed line operator systems to VoIP. In today’s climate the savings are hard to ignore and most hotel managers are very interested in understanding how this can work for them”. We are presently converting two major hotel groups to the G7Eleven VoIP platform”. Nick Whittome, Director G7Eleven

G7eleven is an Irish owned company that is providing innovative VoIP solutions to all businesses helping them to break free from high fixed line rental and mobile costs.G7Eleven was set up as the result of two IT business owners putting their heads together and seeing that in Ireland, there was a distinct lack of professional, technically minded, reliable IP phone system providers. On top of that, there was also no reliable, cost effective VoIP trunk provider. For this reason, Shane Hartigan and Nick Whittome established G7Eleven to tackle these problems and to finally provide a total solution for companies throughout Ireland. It’s time for G7Eleven, its time for New Thinking.

Save Money. By moving to a G7 Eleven VoIP system you will instantly eliminate the rental cost of Primary, Basic or PSTN line rental, in some cases this can be €300 or more per month. Up to 50% savings can also be achieved on all outbound phone calls.

site in order to resolve any issues and minimise any disruption that may be caused.

Customer testimonials
“We recently moved offices and were looking for a more cost effective telecoms solution and decided to move to the 3CX Windows PBX using the G7Eleven VoIP trunking service. We can now monitor all inbound and outbound call activity from our PC’s and have also achieved significant cost savings. G7Eleven installed this system seamlessly and we are very pleased with the results achieved to date.” Donagh Madigan M&C Property Management “We recently brought 2 separate doctors surgeries together into one and moved from an antiquated phone system to the most advanced telecom and VoIP system on the market. G7Eleven provided us with amazing customer support and set up of systems and we are now reaping the rewards with reduced phone bills and no fixed line rental.”

There are some important pieces of information missing from that blogpost.   The first most important piece of information is that this method will only work if the PC is domain joined.    Microsoft have in their wisdom not enabled this feature for standalone PC configurations.

The next obvious problem with the 3CX post is that the method they mention would tag ALL packets leaving that machine with priority.   Obviously this is not good if the machine is downloading updates, or generating other traffic out via your router.

Follow the process on the blogpost from 3CX, but at the point when you add the rule, make sure to specify the following applications: (you need to add three QoS rules).

3CXMediaServer.exe
3CXPhoneSystem.exe
3CXTunnel.exe

Which will look like this in your Group policy editor after you have added all three rules:

Once you have added the rules, the packets leaving your network should be immediately tagged so that you can go ahead and configure your router to prioritise the traffic.

G7eleven will be exhibiting at the Irishwireless.net Wireless ISP Conference & Expo

The event is taking place on Thursday 31st March at the Louis Fitzgerald Hotel, Naas Road, Dublin.

We will be exhibiting our SIP Trunk service for end users and also resellers interested in cost effective “White Label” solutions.   We will also be demoing the 3CX Windows Based PBX system.  If you are interested in attending, you can register here.

Recently, G7Eleven completed a large scale wired and wireless network installation for a College Campus and as part of this project deployment we implented a 3CX VoIP solution that takes full advantage of their new network.

The customer has twenty eight Zone Director managed RUCKUS wireless AP’s throughout their campus property and G7Eleven has limited their VoIP traffic to a special encrypted VLAN. All is working well except one major issue.

Sometimes during a call their WiFi phone roams out of coverage. This is a rare occurrence thanks to the excellent performance of Ruckus Wireless (www.ruckuswireless.com) but it does happen from time to time no matter how good the wireless coverage is.

This is a serious problem as 3CX does not disconnect the handset and the previously live phone call is not cleared by default until the system administrator intervenes and manually closes the call in the 3CX management console.

To make matters worse, when the WiFi phone re-associates to the wireless network it cannot make any further calls until the previous call has been manually cleared. The handset has no knowledge that it was previously on a call and fails to re-register back to 3CX properly and make further calls.

This was very inconvenient for the customer and needed a solution fast.

I therefore had a question?

“Is there a timer in 3CX or setting that I could change to clear the call in this circumstance?”

The answer when it comes to 3CX is of course “YES”

Check the Custom Parameter with name “SIPPINGPERIOD” in 3CX.

Normally this is disabled and when it is enabled it queries the handset so I set the value to 20 seconds. I did not want to set it too short in case the customer lost coverage for a short period of time, for example when they step into a lift during a call and then exit and reconnect to another AP then this call would continue perfectly.

I made a phone call from a WiFi Handset and while on a call placed the phone into a metal box (USA Biscuit Tin actually, aka high tech WiFi signal blocker and very yummy biscuits too..) and after 5-10 seconds the handset lost wireless signal. The call remained open on the 3CX system and after approx 20 seconds was cleared when 3CX SIPPINGPERIOD failed to get an answer from the handset.

Objective achieved. Hope this helps someone else.

• IAX2 does not return correct HANGUP CAUSE codes! So solving interconnection problems between servers can be difficult.
• IAX2 can only use 1 thread – that means it can’t handle a lot of calls at one time.

Also:

All received packets go through 1 and only 1 thread because of the way that udp is done and the fact that they are all going to the same port. This means that for reception you can use 1 and only 1 core/cpu.

From a provider point of view this is not good.
