Using Cisco cp-8811 as landline

Truckermal

Hi Folks.

I have Eir FTTH with the Eir router (new connection) and have a Cisco phone. The phone needs a PSU which I don't have or a router capable of powering it. It takes 48V DC to power it using a PSU.

Any ideas on how to get this working without buying the PSU as they are expensive.

This is it

48v POE adapter/injector

I was looking at them on Amazon and they are about €60 someone was saying you could use the router as a Power supply..

Not going to happen. Doesn't eir supply a PSTN port for a normal phone and line?

What are the phone specs?

These things are designed for routers with PoE injection but the Spec would suggest that a basic IEEE 802.3af PoE Injector should work using a non PoE router.

Why not a 48V PSU?

Just get a 48v injector.

This is an IP phone, you’re going to need a SIP server to run it off.

One would guess that if he had an IP phone, he had an account with blueface or goldfish or similar.
