How to set up VoIP inside local network without a VoIP server?

Daimkhanna — Sun, 08 Aug 2021 06:21:51 GMT

I have a task to set up VoIP inside a small network (~20 Cisco IP Phone 303). Only for calls inside the local network. I have no previous experience with VoIP and I want to do everything in the most simple and reliable way.

After some googling I still have a question - is there a way to set up all ~20 phones manually, so there will be no need for VoIP server (e.g. Asterisk)? If yes, I will be grateful for any guidance, links or other material.

Hi,

No, you need to have a central server which is responsible for signaling
between the phones (like the brain of the system).

A call server is required.

For 20 phones, an Asterisk hosted onto a Raspberry Pi is achievable.

Peer to Peer 2 Phones will be good to testing, but for 20 Phones you need a mini SIP PBX.

If you looking you can use call manager if you looking any Open source :

as you mentioned (Asterisk is good) - but FreeSWITCH is good for me (https://www.fusionpbx.com/ - i was part of this not-owner, way back i was in touch with developer (owner)when i was doing some multi-tenant PBX system for Call centers - it got a nice GUI and is easy to install).

if you looking asterisk based: https://www.freepbx.org/downloads/ - still good

Both have many how-to

You'll need something to connect the phones to. You either connect them to a gateway on your LAN or on your ISP's network.
