# Public Announcement (Intercom) using the MLML Cisco Phone

**The Cisco Bogen PA for the main building hallway works as follows:**

1. From any MLML Cisco phone using the hand set for speaking, do not use the speaker as it is prone to feedback, dial 14101.
2. Listen for 2 beeps.
3. Dial 00 (zero zero)
4. Listen for announce 'tone' (only played through the speakers in the hall), or you can also wait 2 full seconds.
5. Make your announcement, this is a real-time announcement.
6. Depress the Release Button or Handset button to hang-up and avoid making a loud noise. ![](https://kb.mlml.sjsu.edu/uploads/images/gallery/2019-02-Feb/scaled-840-0/image-1550619960463.png)
7. Hang up.
