Based on the linked and your previous questions I think you mean oceanic position reports.
Here's what ICAO Annex 10 Vol II says:
5.2.1.9.2.3.1 PANS.— An aeronautical station should acknowledge position reports and other flight progress reports by reading back the report and terminating the read back by its call sign, except that the read back procedure may be suspended temporarily whenever it will alleviate congestion on the communication channel.
An "aeronautical station" will typically have the radio suffix, e.g. Santa Maria Radio (LPPO) over the Atlantic.
Examples
You can listen to such exchange with Gander Radio over the Atlantic on YouTube here, also:
A South African AIC (41.3) on Radiotelephony Procedures provides an oceanic position report example for the quoted Annex 10 paragraph:
16.5 [same exact text as above quoted 5.2.1.9.2.3.1]
NOTE: the following example illustrates the application of this procedure
(Network station acknowledging receipt of position report)
Aircraft:
JOHANNESBURG OCEANIC SPRINGBOK SIX ZERO WUN – WUN AIT AIT SIX WUN
Station:
SPRINGBOK SIX ZERO WUN – JOHANNESBURG OCEANIC – GO AHEAD
Aircraft:
SPRINGBOK SIX ZERO WUN – OVERHEAD UBVER AT WUN SIX – FLIGHT LEVEL WUN AIT
ZERO – ESTIMATING EXAKO AT WUN TOO TREE AIT
Station (acknowledging):
SPRINGBOK SIX ZERO WUN – OCEANIC COPIES UBVER AT WUN SIX – FLIGHT LEVEL WUN
AIT ZERO – REPORT AT EXAKO NEXT
Aircraft (denoting correctness of readback):
REPORT AT EXAKO NEXT SPRINGBOK SIX ZERO WUN
