Checking status

Your number. Your network. Free.

Sign up, confirm your e-mail and your phone line on CorePBX.net is ready. Ring anyone on the network from a browser tab, an app or a desk phone – it never costs a thing.

How it works

What your line can do

Everything below comes with every account. No hardware needed, but every SIP phone works.

Make and take calls

  • A line number of your own, picked by you with premium
  • Dial right in this website, or sign in a softphone or desk phone (SIP over UDP, TCP or TLS, optional SRTP)
  • Every device you sign in rings at the same time – and Discord too, if you like: answer and talk in a voice channel
  • Reach regular phone numbers through the network's phone line

Stay reachable

  • Mailbox with your own greetings; messages play in the browser and arrive by e-mail
  • Forward calls or switch on do not disturb, also with a quick code from the phone
  • Premium call queue: callers wait in line with music while you finish a call
  • Alerts by e-mail and, if you like, as Discord direct messages
  • Fax inbox: fax machines reach you on your normal number; send faxes from the website or Discord

Group calls & paging

  • Group calls in your own rooms, with PINs and host controls
  • Speak straight into someone's phone, or to a whole group at once
  • Record a message by phone and the bot posts it to the Discord server
  • A live list of who is online and free to talk

All calls are secure and private

Nobody listens in and calls are never recorded, unless someone on the call switches on call recording, which everyone hears announced. Calls from the browser are always encrypted, and desk phones and apps can use TLS and SRTP. Your details and recordings are stored encrypted, and two-factor sign-in is one click away.
