Hi all the people in the list!<br><br>I'm new on this list, this is my first post.<br>I configured asterisk 1.6 with freepbx 2.7 and dahdi to send faxes with t38modem conected to hylafax as a sip extension of asterisk.<br>
Everything is supposed to be configured fine, the faxes start sending, but at the middle of the transaction, it fails. The T.38 termination provider told me that they were receiving a=T38MaxBitRate:2400 on their asterisk, and told me that this issue could be the problem.<br>
I've checked all the configuration and can't see any kind of configuration for the bitrate of the t38modem.<br>I don't know if this is an Asterisk issue or a t38modem issue.<br>My configurations are:<br><br>/etc/asterisk/udptl.conf:<br>
