Many modern companies using voip provider services need to send/receive faxes via IP PBX. Asterisk 1.4 supports the T38 protocol in the "passthrough" mode for SIP-channels. In this article you will learn how to set up T38modem to send faxes via Asterisk PBX. Note that Asterisk 1.4.19 has a bug, because of which the above example configuration will not work, so it is recommended to use version 1.4.20.
Since Asterisk does not support T38 protocol for H.323, T38modem program should be set up with the support of the SIP protocol. To do this, you need OPAL. Remember that T38modem is not compatible with versions of the OPAL, released later than May 2007. It is strongly recommended to download the necessary libraries and T38modem program itself in the home directory; otherwise there may be some problems in the future.
Running T38modem, you'll see some basic logs on the terminal used. Full log will be recorded in /var/log/t38modem.log.
