NVFaxDetect make Asterisk die

Asterisk Asterisk Support

Hi

I am using:

  • Debian Etch4.0r6, x86, VMWare Server 2 (also tried x86_64 on VMWare Server 2)
  • No Zaptel
  • No libpri
  • Spandsp 0.0.4pre16
  • Asterisk 1.4.23.1 (also tried 1.4.17)
  • NVFaxDetect, app_rxfax and app_txfax from SVN AGX Asterisk Addons
  • FreepBX 2.5.1

PSTN connected to Grandstream GXW4104 (configured with T.38 pass-through), and this connected to Asterisk through SIP. I have configured the fax detection on FreePBX in inbound routes with NVFaxDetect. When I make a voice call, the call is redirected to the destination configured in the inbound route (an extension); this is correct. But if the call is a fax, i get this on the CLI:

pbx-leovinci*CLI>

And Asterisk is restarted. Why does this happen? How can I get more info about the crash?

Thanks in advance.
