Some companies have an 86 10 in front of their fixed telephones. What does this 86 10 mean?

86 is the international area code of China, and 10 is the area code of Beijing.

In the international telecommunication system, you need to dial zero when dialing the telephone number, which is the commonly used area code 0 10, 020, 02 1 and so on. You need to dial 0+ area code when dialing foreign numbers, but it is unrealistic to dial this 0 when dialing caller ID. When a foreign country dials China, it must dial twice (first from the local bureau and then from the national bureau, so two zeros must be added.
