Hi all,

A complete noob here and looking to set up 5-6 cordless phones (Yealink W56H maybe) and I would like the ability to have these phones

  • connect with each other via a PBX system to make voice only calls (no video calls or multimedia calls etc.) and only assign a single digit extensions for dialing to each one of these phones
  • ability for external outgoing calls using a single phone line and maybe expand that to 2 phone lines for making 2 simultaneous incoming/outgoing calls for a month during a calendar year (my understanding is I would need a SIP trunk line for this)

I would like everything on-prem and nothing hosted on the cloud at all.

I have reached out to some local resellers and tried looking this up online but likely getting confused because everyone is giving me different information.

In a nutshell, this is what I have been advised

  • I would need an on-prem hosted SIP server - 3CX is the best one?
  1. Some have said that I cannot have an on-prem PBX system that supports IP phones - unsure why this would be the case though.
  2. This has to be on a very powerful server hardware to support all the voice codecs
  3. I would have to pay for an annual license cost for this server to run 3CX SIP server - the website says it is perpetually free for up to 10 users but unsure why all the resellers are charging annual license cost to us
  • All the cordless handsets would need a base station each even though one base station can support up to 5 handsets
  • We cannot assign single digit extensions to these phones via the SIP or the PBX system

TIA
