A city council may hold a meeting via telephone conference if an emergency or public necessity exists and it is impossible or difficult for a quorum of the city council to meet at one location. See Tex. Government Code §551.125(b). A notice of the meeting must be posted, specifying the location of the meeting as the same place where the meetings of the city council are usually held. Id. at §552.125(d). However, the notice need not specify that the meeting will be held by telephone conference. See Tex. Attorney Gen. Op. No. JC-352 (2001). The meeting must be set up to provide two-way communication during the entire meeting and the identity of each speaker must be clearly stated prior to the speaker speaking. Id. at §551.125(f). Additionally, all portions of the meeting, other than closed executive sessions, must be audible to the public at the location of the meeting, must be recorded, and the recording made available to the public. Id. at §551.125(e).
