If the Public Security Bureau comes forward, can the Telecommunications Bureau find out the specific content of the voice calls on the mobile phone?

At the telecommunications bureau, most people can only check the call records, but not the specific content of the call. If you have a voice message in advance, the telecommunications bureau can check it, but individuals cannot check it. Only the public security organs can inquire and present the corresponding documents. The specific content and SMS number of the text messages on the mobile phone can be found. The Anhui Telecom public account is at your service.
