A method for conference access includes: receiving, by a switchboard device, a first call request sent by a user terminal, where a calling identifier included by the first call request is an identifier of the user terminal, and the included called identifier is a switchboard number corresponding to the switchboard device; obtaining, according to the identifier of the user terminal, recorded information about a conference corresponding to a call missed by the user terminal, where the information about the conference includes an access number of a conference system to which the conference belongs and a conference identifier of the conference; and enabling the user terminal to access the conference. When a user misses answering a conference-related call, by dialing a switchboard number, the user may directly accesses a conference, thereby improving the efficiency of accessing the conference.
