I have successfully installed freepbx on top of Ubuntu 8.04, can call extension to extension, call in and out of a trunk, have voicemail set up, and receive emails of left voicemails.
I am now trying to get fax reception working – I have a dedicated SIP DID that I want to use for inbound faxing.
I installed the ubuntu package asterisk-app-fax. When I call the pre-configured special fax extension 666 from another PBX extension, I get the appropriate fax reception ‘canary calls.’ With an inbound rule set up, when I call the designated DID from outside the PBX (whether via SIP or PSTN), I get mapped to this extension with no problem, and receive the canary calls with no problem.
However, when I have a fax machine do the calling, the fax starts to go through, but then interrupts in the middle. Scanning the log file, the most relevant error messages seem to be that included below. Granted, they’re all warnings, but the bit about not finding a codec mapping concerns me.
Has anyone any idea what the problem could be here?
