I was hoping to get some feedback on a Voip system based on trixbox. This is the scenario:
-Main office has 4 phones and 2 or 3 PSTN lines.
-Local offices (within 50m of main building) will each have their own phone number which will be allocated to them by the main office. Roughly 30 different numbers so ISDN is the best way to go here.
-PSTN lines and ISDN lines are connected to a Trixbox server.
-Softphones registered with the sever.
-Incoming calls automatically route to the correct phone, if it is busy or unanswered it will route to the main office reception and display caller info.
-Outgoing calls will route over PSTN/ISDN lines depending on which handset is used.
-There are a number of external offices that currently have regular landlines and handsets.
-We want to install an ATA box at each office and route calls back to the trixbox, and then to main office when a call is unanswered or phone is busy. Call info will display on main office handset.
-Preferably office would use regular handset
-Outgoing calls route over PSTN network
-Calls being transferred will route over the internet to the trixbox.
Main office will have a 512/512 ADSL connection
External Offices will have at least 512/256 adsl connection
-What issues do you see arising with this system?
-Is it a big deal to setup PSTN and ISDN lines on trixbox? What is invloved in getting them to route to the correct phone?
-How do we connect fax lines?
I think that will do for now
Thanks for your time, I really appreciate it
