Our company, located in Greece, is about to open an office in Dubai. We are trying to make a plan concerning connectivity with our headquarters in Athens, which means the ideal solution for us would be VPN and VoIP (asterisk) over ADSL.
We have no idea what ISPs exist there, and whether there are limitations in the field of over-adsl-connectivity (or maybe there's some other connection, metro ethernet/fiber/SHDSL or whatever used widely?). Googling didn't provide a definitive answer, ISP sites are a bit overcomplicated and for some reason all i found seems like it's based on mobile phone networks - or maybe I just don't understand what is offered there.
Could someone please provide some info?
