Technical Overview

To operate a telephone "network" there's a few things we need to consider.

Numbering

Numbering makes up a big part of telephony. We propose a hierarchal approach so numbers can be split between organisations and their sub-organisation, with the potential for more granularity.

For more information, see Numbering

Routing

To route calls between entities, we propose the use of an ENUM like system where telephone numbers are mapped to URIs via DNS records.

Whilst ENUM will make up the core of the project, there's scope for translation services such as a SIP 302 redirect server or a HTTPS API.

For more information, see Routing

Security

Securing such a network is made up of several parts:

• Authenticating connections between entities. See Encryption and Authentication
• Encrypting the Signalling and Media. See Encryption and Authentication
• Verifying the Caller ID. See Verification
