System Requirements for Touch-Tone	4
Receivers

A voice messaging system requires a certain number of TTRs in addition to any system requirements for TTRs. The number of TTRs depends on the number of ports used by the voice messaging system (see Table D–1). TTRs are also required in private networks using E&M, T1 tie, and tandem tie trunks.

In Release 6.0 and later systems, the use of the Prompt-Based Overflow setting, which allows callers to request overflow coverage while waiting in a calling group queue, requires TTRs for primary and secondary delay announcement devices that present the option to callers.
