Three out of four of my Aastras have crapped out, into "web recovery" mode. I'm still trying to figure it out, but I'm starting to suspect the power supplies failed and corrupted the firmware.
They all failed within weeks of each other. Roughly six years old.
Wow, that's not good.. I have a 9143i, roughly the same age. Hopefully I do run into the same. I love that phone. Have you tried to contact Mitel? (they tool over the Aastra phones). Maybe you can still perform an update for your model via TFTP. Good luck.
I just stepped into the world of VOIP with Voip.ms and am using a Cisco SPA509G. The thing is built like a tank. Awesome sound quality and seems to be highly configurable - but not the easiest to do. Overall - a solid unit though. I also have a Cisco SPA525G I'm waiting to get a power adapter for. Once I get it it should work using WiFi.
All IP phones connect to a network like any other networked device (hence the name, IP phone). How you connect to the internet depends on the services available to you.
Does PoE mean the phone gets its power from the computer instead of using a wall wart (power adapter)?
My connection question wasn't clear. I meant to ask: for a basic network with one computer, one modem, one IP Phone, (no other devices) would the IP phone connect via ethernet cable only to the modem and to the computer? There wouldn't be any need for telephone cable between anything, would there?
No PoE is Power over Ethernet. You need to use a PoE switch. Netgear make some "economical" ones like the Netgear GS110TP. This will provide the power you need to power up IP phones.
If you have one modem (Cable or DSL?), you very likely have an "all-in-one" modem-router-WiFi which you'll likely have 4 LAN ports. This is not sufficient for PoE. Instead of using a "Wall-wart" because I'm guessing you only want one cable going to your phone, you could also consider a power-injection adapter. This still has a wall-wart, but it will also provide PoE to one device. This would be able to run one network cable up to your phone. Which IP phone do you have?
With Power over Ethernet (PoE), power is carried over the Ethernet cable, usually from a PoE switch, though injectors may also be used when a PoE switch is not available. An injector is typically used when there aren't enough PoE devices to warrant a PoE switch. On the other hand, when there are many PoE devices, such as VoIP phones, then a PoE switch is preferred. PoE can be used to power all sorts of devices, such as phones, WiFi access points, security cameras and more. Like any other switch, a PoE switch has to be connected to a power source, usually AC.
An IP phone connects like any other network device, it'll need an IP address, a Gateway, knowledge of what DNS servers to use, and find a time server (SNTP).
Extra things that an IP phone needs is to be able to find a provisioning server. This server could be an TFTP, FTP or HTTP(S) server, that provides configuration files, new images and log files for your IP phone to be able to boot up.
Once booted, the phone will also be looking for a registration server (wherever you have voice services configured). This could be a local "PBX" like an Asterisk server, or it could be a service like voip.ms
Certain models may vary depending on the manufacturer, but they basically all work the same way.
So I would just hook up the IP Phone like an ATA device, by connecting it to my modem and to my computer via ethernet cable? Then making all the necessary provisions?
Only if connecting off the local network. If you have a VoIP PBX on your local network, you don't need either of those.
