7.7.8. Call—Automatic Pulse Dial
Table 140 lists the commands that occur after the configuration defined in Table 136.
7.7.9. Answer
A ring event will prompt the user to press the speakerphone button. This will generate a SP Button On Event and
the Speakerphone Configuration procedure defined in Table 136 on page 219 should be used to answer the call.
For ring detection and local ring tone/melody generation, see "7.6.2. TAM Hands-Free—Idle".
7.7.10. Handset Transition
For a SP Button Off Event (Handset Off-Hook), the voice driver should use the command sequence in Table 141 to
return to the Handset mode. Note the voice driver is responsible for tracking the handset hook switch state.
