What modems are support the AT command of activate voice?

What modems of Wavecom and Sierra Wireless support the AT command of activate voice? And what this AT command? For example AT^CVOICE= for Huawei. Its function can possible translate voice with PC thougth USB interface into GSM network.

Hi,

Most products support voice by default.
For “translate voice with PC thougth USB interface into GSM network”, are you referring USB audio? If that’s the case, OpenUSB feature in OpenAT Application Frame will do.

Hope it helps.

Wavecom q2406b are supported?

Q2604 supports analog audio but no USB interface.
