Is CUG and PNP supported

Dear Asterisk

My name is Masayuki Arai.

I research on PBX technical specs.
So, I have some questions about Asterisk.

  • Is Closed User Group (3GPP TS 22.085 or 3GPP TS 24.654) supported ?
  • Is Private Numbering Plan (3GPP TS 02.95) supported ?

Closed User Group (CUG)
3GPP TS 22.085: Closed User Group (CUG) supplementary services; Stage 1
3GPP TS 24.654: Closed User Group (CUG) using IP Multimedia (IM) Core Network (CN) subsystem, Protocol Specification

Private Numbering Plan (PNP)
3GPP TS 02.95: Support of Private Numbering Plan (SPNP); Service description; Stage 1

Probably not, no.


Dear Malcom,

Thank you very much for the information.

Sincerely yours,
Masayuki Arai.
