The Band Committee of 100 people wishes to set up a telephone call system. The initial contact person calls three other people, each of whom call three others and so on, until all the people in the Band Committee have been contacted. What is the maximum number of people they need to make the calls.

If you aren’t sure how to do this mathematically, it’s easy to do with a simple diagram.

The first person calls 3 people. (1×3) – 3 calls so far
Those 3 people in turn call 9 people. (3×3) – 12 calls total
Those 9 people in turn call 27 people 3×9) – 39 calls total
Those 27 people in turn would call 81 people except that you’d go over the 100 call mark. So 7 of the 27 will make 3 calls and the other 20 will only make 2 calls – 61 calls + previous 39 calls = 100

So 27+9+3+1=40 people would be the maximum number required to make the 100 calls.

Any advice on the whole system would be great.

I currently have a BT line and service and Sky TV with broadband package. Most phone usage will be evenings and weekend.

You don’t need a VoIP compatible phone to use VoIP. You can use a regular telephone that plugs into a VoIP router. Most VoIP companies either charge very little for the router, or offer it free when you sign up for a plan.

One of the disadvantages of having a regular telephone plugged into a VoIP router is that it will be the only phone you can use. The fix for this is to get an expandable VoIP phone base. This is a VoIP phone with the router built in, and makes it possible for you to have multiple handsets throughout your home just like with a landline phone. This is why a VoIP compatible phone can be a bit costly.

There is a way to beat the high price of a VoIP compatible phone though. I highly recommend Packet8 since I use them for both my business phone, and residential. You have a choice to pay monthly, or yearly, and if you get an unlimited calling plan you can get a free VoIP compatible phone expandable up to 10 handsets, or an even nicer one for $19!

The biggest advantage of VoIP phone over a traditional landline is cost. Hands down. For example with Packet8’s Freedom Unlimited plan you can get unlimited local and long distance calling in the US,Canada, Puerto Rico, Guam, US Virgin Islands, France, Italy, Ireland, Spain and United Kingdom, plus unlimited in-network calling to other Packet8 subscribers worldwide for $24.99 a month

There are other VoIP phone services providers with even cheaper calling plans, but in my opinion Packet8 is the best value overall.

What are the differences between IP-PBX and normal PBX systems. We have roughly 14 employees so would need around that many phone lines of similar numbers.

Thank you.
P:s could you also link some product if u have in mind thanks.

A traditional pbx system is going to be a hardware solution to plug all of the telephone lines into. While a virtual PBX is going to be a software solution. IP phones work particularly well for a virtual PBX because all of the phones are connected to your LAN within the office.

Here is a link to Axon which is a very cost effective virtual PBX that you can combine with other application to make a complete phone system.

for example add IVM for an auto attendant and voicemail, and/or IMS for advanced on-hold messaging capabilities.

You can use this system with either VoIP telephone lines which would be easiest and cheaper if you decide to go that route, or you can use it with your standard analog landline phone lines too, but you will need additional harware in the form of a telephony board or fxo adapter to connect the phoneline(s) to your computer
(ex. http://www.altoedge.com/telephony/index.html )

Since you mentioned IP here are some IP telephones that you can take a look at:

I hope that is at least a good start to an answer for you!

Please help!!! Does anybody have any ideas as to how much this would cost roughly?

Any help given is much appreciated!!!
I am using a wireless network. It is not my LAN that needs replacing. It is my actual phone wiring. It is a pre-1980 system and a lot of the wires are damaged and have bare wiring exposed.
I definately have a problem with the wiring.
Also, I have contacted my provider. The ran a speed test. I get maximum speed external to my house, but I dont seem to get this speed from within.

Yoou are talking DSL…you need to know the distance of the loop length…which is the distance from the telephone office to your house and back again.

I jumped through all sorts of burning hoops to figure out why my DSL was so erratice. The phone company told me my wiring, my computer, and then after weeks and many phone calls they told me I was too far from their office.

I went with cable broadband and no problems.

wireless phone jacks act as a transmitter and reciever… the reciever needs power to get the radio signal from the base or transmitter… so any cordless phone system, or cordless phone jack (which i do not ever recommend) will need power at the transmission and recieving point..

The UK had a very old fashioned system under the GPO which was a government run phone company. In the 1980s the service was sold to BT. But the odd of it working just the same as Singapore is slim to none.
