When talking to the little girl, Olivia mutes the polycom speaker phone device as the girl recites a rhyme so she can argue with captain Cragen. The LEDs on the polycom speaker phone device change from Green to Red to indicate the phone has been muted. In the next few seconds, Cragen makes a statement about how the traffic sounds are looped in the background and the as the camera follows him as he moves closer to press a button, the polycom is shown to be illuminated in green (unmuted). In the following seconds Olivia is shown unmuting the phone, turning the LEDs from red back to green.
At about 11 minutes in, Olivia mutes the speaker, to talk to Cragen. She does not unmute it, when she next speaks to Maria, but Maria hears her, & answers her.
Maria tells Olivia that when she lived with her mother in Honduras, she had a cat named Chimichanga ("You know, like the food," she says). Chimichangas are an American invention, and while they can sometimes be found in northern parts of Mexico, they wouldn't exist in Honduras.
