I am new in VoIP Networks. I just have a project to build a Small VoIP Network. Actually, i want to use SimBox (For Mobiles) or PSTN (For Landline) Analogue Line as my trunk line and want to link them by SIP Server or IP PBX over the Core Network.
So can you sketch the Network Layout with usefull devices and products.
I'll be very thankful for your kind help
