Voices from the Dark is a side quest in Deus Ex: Human Revolution.

Introduction
If Zeke Sanders escaped during the Neutralize the Terrorist Leader mission, either if Jensen let him go immediately or after convincing him to let Josie Thorpe go through conversation, Zeke will want to meet with Jensen.

Once Jensen has been assigned the Stopping the Transmission mission, Pritchard will contact him when leaving the Chiron Building saying one of Jensen's contacts has left a message to meet him in an alley off Bagley Avenue, near the Sarif Building.

Meet Zeke Sanders
Zeke is found in an alley near the Sarif Building as indicated. Simply head to the marker and engage him in conversation.

He will give Jensen a pocket secretary with access codes and some miscellaneous information regarding the FEMA complex.
