Hello friendsters and * users.
I am running a small company with two branches. I used to be located in our HQ in London,
but due to my family situation I must stay home in Greece for the better part of the year.
This has proven to be extremely costly for my company. The phonebills have skyrocketed.
We have one branch in sweden in addition to HQ in London.
The business model forces heavy use of telecommunication, some email but mostly plain old telephone and faxes.
We are in a very competative field, and because of our low overhead we need to lower our cost.
I have done some reading about asterisk, and from what I gather we will need this:
3 servers to run asterisk,(1 in UK, 1 in sweden and 1 located in greece) with the needed add on cards.(TDM400p), the number of TDM 400 cards is for me not clearly understood but I am sure you will find it out after reading the rest of the list
Providers of VOIP phonenumbers for UK, Sweden and Greece.
I am unsure to what to search for here, so let me know what such providers are called, and I am sure I will find some.
Find a way to call at local price to UK, Sweden and Greece, from any of the mentioned locations.
Recive phone calls in Greece from Sweden and UK where our clients (the caller) pays local price.
5.For our London office we will need 4 numbers (where people can call in/out), and 10 internal numbers, called extensions I belive.
The Malmo office will need two numbers, and 6 extensions.
My home in Greece will need 3 numbers, 4 extensions and the possibility to recive forwarded calls from any of the two other offices at local price.
When not in the office I will need to have calls forwarded to my Greek cellphone, how can we manage that at local rates? This goes for forwarded calls from
any of the two offices, or calls that are placed to any of the three Greek numbers. The calls can not be forwarded to a UK cellphone, cause of the extra roaming charges.
Likewise will any emplyee in any of the two other offices need to have calls forwarded to their swedish or english cellphone, if they are out of office.
10.I understand that all this will require multiple providers of telephone numbers, but I have no clue what to expect to pay for monthly fee for that or if it even excist providers that will deliver a service where one only pays for the actuall calls made, without any monthly costs.
- Does it excist “no-name” cards that one can use rather then the TDM 400? Maybe at a lower cost?
12.Also one should have a clear vision of scalability, because we hopefully will need to hire more people during this year, and that would require additional cards, and even more CPU from the servers, right? If we set up p4 4ghz pc’s with 1 gb ram, does this set up allow us to scale up, say double the number of users without noticing server stress and lag?
Have done some searching, and what I find is that I might be able to opt for a VOIP service from several providers. I have found VOIP that charges a reasonable per minute fee, and no monthly fee, and I am ok with that.
What is the difference between VOIP and DID and similar things?
If I have one adapter thing from each VOIP provider in my home in greece, will I then be able to make call plans based on lowest prices? I mean that if I pick up any phone in the house, and dial a UK number, will the asterisk be able to choose the correct VOIP provider directly, or will I need to have one specific phone to each VOIP provider?
I aware of the great wiki, but my poor english is prohibiting me for a clear and in depth understanding of all this. So when helping me out please explain in the smallest words possible. And belive me, technical engllish like this, with lots of special terminology is hard to get translated ;D)
