Hi, I'd like to know if IAXmodem already supports fax speed transmission at 33.6kbps. I've found from this page (https://www.voip-info.org/asterisk-iaxmodem/) that: "Iaxmodem uses the spandsp library. So currently its modulation protocol support covers V.27ter, V.29 and V.17. V.34 (Super G3) support is not available, and won’t become available in the near future for patent reasons..." Which means that fax speeds from 2400 bps to 14400 bps are supported. However, I dont know how long has been since...
