iaxmodem uses the spandsp library. So currently its modulation protocol<br>support is limited to V.27ter and V.29. Partial (sending) V.17 support<br>is available. V.34 (Super G3) support is not. So those are fax speeds
<br>2400 bps through 14400 bps for sending and 2400 bps through 9600 bps for<br>receiving. Most new fax machines that you would purchase off-the shelf<br>would support either 2400-14400 or 2400-33600 depending on whether or
<br>not it supported Super G3.</blockquote><div><br>So, the suggested design for a fax-enabled PBX solution could be :<br>- for an "average fax use" (faxes from time to time, no fax mailings, telecom budget capable to bear longer durations for fax sendings), use an Asterisk-Hylafax-iaxmodem or your ITSP offering
<br><br>- for an "intermediate fax use" (fax mailings from time to time, sensitive telecom budget), use an Asterisk server with TDM passthru and a dedicated Hylafax fax modem equiped server or dedicate some PSTN lines to a fax server
<br><br>- for an "intensive fax use" (all day long fax mailings, high cost sensitivity), use a dedicated Fax Service Provider with competitive offering in the areas you are fax-mailing to.<br></div><br>What do you think of that ?
