Understanding PBX's and VOIP

Hi

My company is looking at new phone systems, one of them being VOIP.

I had some questions.

1. If we had VOIP, are all internal<>internal calls free?

2. If we had VOIP, are all internal<>external (where the external party has VOIP too) calls free?

3. How does VOIP costing work if we have VOIP but the other recipient of the phonecall has a standard, digital, line?

4. I understand with some PBX solutions, it's possible to connect to the PBX via Wi-Fi. Does this mean all mobile <> internal calls are free, as well as all mobile <> external? Or, rather, would the mobile <> external calls be charged at the landline cost rather than the mobile cost?

If properly setup:

1) Yes, if you exclude the cost of the phones, pbx, and internet connection
2) No, somehow you need PSTN access.  This costs money
3) You use PSTN from your VOIP system or someone elses so you pay PSTN rates.
4) The simple answer is wireless doesn't change much, internal free external is PSTN access.

IF you want to experiment, you can download a free voip PBX.  There are instructions to setup PSTN access.

Thanks both

Regarding experimenting, is it possible to set up a test PBX, that's possible?

Also, I have a list of PBX's that our company maybe moving to - how will I know if it's VOIP or not? Does anyone know a site where they're listed? Avaya 5 is one of the possible mentions.

1. Yes.
2. Can be free if you know their VoIP address but it can be awkward to dial. You could use a VoIP call provider who gives free landline calls to make the call and just ignore their VoIP.

3. Digital or Analogue line - doesn't affect the situation. If you have VoIP you use an outgoing call provider and pay them for the calls. There are many out there - some give you free landline calls others charge a little.

4. Wi-Fi is NOT Mobile. You can use Wi-Fi to connect a VoIP device because it justs extends the network - but you need to be aware of the high traffic levels of good quiality VoIP calls.
Mobile calls are relatively cheap through the VoIP outgoing call providers (at least some) - shop around.
