Using Modem as Dialer Prior to VoiceView Mode
To use the modem to dial a call, the modem must be in Voice On-line mode (via #CLS=8) to dial before enabling VoiceView
mode. VoiceView mode can enabled by the AT+FCLASS=80 parameter after Voice On-line (VCON) mode in handset,
speakerphone or handset emulation modes. The modem can be switched between handset (#VLS=0) and speakerphone
(#VLS=6) modes during +FCLASS=80, as described in the previous section.
Example 5

VCON Call established.
AT+FCLASS=80 Enable VoiceView mode.
OK
(Establish VoiceView Data Mode using normal VoiceView
procedures.)
Continue with speakerphone conversation.
ATH Terminate speakerphone call.
