<div dir="ltr">Hi all,<br>Sorry to interrupt. I need some help regarding fax passthru mode.<br><br>We are trying to configure fax passthru mode in asterisk using sip. For out of network calls/fax we use trunk configuration. i am using asterisk <a href="http://1.4.2.">1.4.2.</a> The user has to use fax machine connected to their ata and dial the callee number, the call is originated just like a regular voice call. have not defined any special context for sending faxes. Have enabled t38 and canreinvite in peer/user and trunk configuration. But the fax is not going thru. Our service provider does support fax passthru. Following is the trunk and user/peer configuration:<br>
