But Motorola code seems to do different magic according to modem type, so things may not be as easy.

            if (pdata->voice_type == VOICE_TYPE_STE) {
                    /* STE_M570 */
                    ret = cpcap_audio_reg_write(codec, 2, 0xAE06);
                    if (rate == 16000)
		ret |= cpcap_audio_reg_write(codec, 1, 0x8720);
                    else
                            ret |= cpcap_audio_reg_write(codec, 1, 0x8120);
            } else if (pdata->voice_type == VOICE_TYPE_QC) {
                    /* MDM6600 */
                    ret = cpcap_audio_reg_write(codec, 2, 0xAE02);
                    if (rate == 16000) {
                            ret |= cpcap_audio_reg_write(codec, 1, 0x6720);
                    } else {
                            ret |= cpcap_audio_reg_write(codec, 1, 0x6120);
                    }

The parts not related to mdm6600 can be ignored until somebody gets some device other modems working with mainline kernel.

And if there are any refrerences to W3GLTE, or wrigley, it supposedly never worked for voice calls and only data.
