i work in a big NGO with several offices all around the world, and i’m seriously thinking to VoIP to reduce our annual bills of telecomunications (i really prefeir our money go to the field and real people than ISP!!!).
I would like to avoid the installation of several asterisk servers on each country (that means also a complex assistence and configuration…not talking about maintenace!), and would like to image a central installation, somewhere on the cloud, shared for each country partecipating to the project…
yes, i’ll have to buy some incoming DID i image, be sure that the internet connectivity of each office is good and stable (and with a good backup where possible), maybe leave just a local PSTN line in case of emergencies…
my question is: anyone tested a similar solution? If yes, did you obtained good cost savings?
do you have any suggestion, recommendation?
thanks a lot!!!
