Due to the ongoing decommissioning of Sprint's iDEN network and the desire to continue to provide push-to-talk (PTT) services to its subscribers, Sprint is offering Sprint Direct Connect, a voice-over-IP system (VoIP) which uses the CDMA network. Customers can keep their old UFMI (Nextel Direct Connect number) or use their phone number as their SDC number. Various enhancements to the PTT services include easier tracking of groups and higher voice quality. A drawback to the system is the inability to work seamlessly with all of the international locations reachable by the iDEN push-to-talk service, though international capabilities do exist.

—Henry David Thoreau (1817–1862)
“Grandchildren are the dots that connect the lines from generation to generation.”
—Lois Wyse (20th century)
