It is very curious what equipment operators use to provide fixed communications.

Equipment for the provision of communication services must be certified. And based on this, you can already find everything you need:
1) City ATS - https://rossvyaz.gov.ru/docs/articles/Gorodskaja_A...
2) MG / MN - https://rossvyaz.gov.ru/ docs/articles/Mezhdunarodn...
3) Rural - https://rossvyaz.gov.ru/docs/articles/Sel6skaja_ATS.pdf
4) Mobile - https://rossvyaz.gov.ru/docs/articles/Sotovaja_pod. ..
5) Institutional - https://rossvyaz.gov.ru/docs/articles/Uchrezhdench...

Absolutely different, ranging from ancient to modern, as well as asterisks / friswitches and the like.

If we are talking specifically about PBXs (and the operator level is SS7 interstation and DSS for customers), then these are Nokia, Siemens, Iskratel, Ericsson, Huawei. SIP is complete, google "softswitch class 4/5".
