I'm just wondering if the users of the fax server have any significant issues when using the fax server feature? For people who do use it, what do you do for outgoing fax?
Do both dedicated and switched mode work equally as well?
The problems with fax over ip is that you need T38 support for it to work perfekt.
Normal voip lines and did numbers have a different compression which up to a certain exent works with faxes but it's not a 100% reliable solution.
I only have some incoming faxes and this seems to work. Outgoing I don't fax at all, scan in the document as pdf file and mail it.
If you do want to use losts of outgoing faxes I would not suggest normal voip as you might run into some problems, 75-80 does come thru but on bad lines it might nog works.
If you want to use voip, by a ata that supports T38 and find a provider that support that. There are not really that many so do a good search.
