What VOIP services without logs and spring?

Question

Telephony

In our company, we need to provide a voip communication channel, without logging, recording and storing calls on our part. Calls to regular landlines mostly. The client ensures the confidentiality of negotiations on his part in any way, this requirement must be met by our company in the first place and we cannot use the services of companies whose servers are located in the Russian Federation due to the spring law.
Please tell me the services that provide voip telephony services that do not write conversations, do not store logs and that it would be possible to pay by bank transfer. Thank you.
