[asterisk-users] Asterisk 1.4.0-beta3 spandsp rxfax woes (or me being hard of thinking)

[Matt Gibson]

Just an update to this..

- my machine was virgin install as well, also tried spandsp located in
/usr/local/lib or /usr/lib
- hard linked the asterisk binary to -lspandsp

still gives the same error :(

As for the "free" line in app_rxfax.so, I commented out:

  ast_frfree(inf);

Once this was commented out, everything seems to work!

Thanks for all the help everyone. My howto will be updated soon.

Thanks,
Diwelf
