Simple to Complex VOIP questions. Part 1...
Posted on 2005-04-22
I am a networking guy who's fairly competent but terribly new to VOIP, and yet I'm left in charge of providing voip solutions to several of our customers. I sort of need a crash course on the different aspects of voip and I would need answers to some questions I will be asking on the coming days. Each question will be worth 500 points and I believe there'll be several ranging from simple to complex issues.
On this first one, I'll be asking the most simple question:
I have 2 offices with broadband DSL connections to the internet (1mbit up, 256 k down.). These offices are in different countries but the connections are pretty reliable.
I want to connect only one phone from office A to another phone located in office B.
I want to dial, say, 8888 on the phone in office A, and the phone in office B will ring. I want to dial, say, 9999 on the phone in Office B and the one in Office A should ring.
I have a DSL modem / firewall doing NAT connected to dumb 100mbit switches in each office. I can do port forwarding etc. that's no problem. I can get faster DSL connections as well if needs be.
I believe I will be needing a device in each office to connect the dedicated phone to, and this device will in turn be connected to the 100mbit switch and will access the internet to reach the other device over the DSL modem / firewall. But there may be other solutions that I do not know of?
I will be waiting for your suggestions.
