Could not locate a FAX technology module

Asterisk Asterisk Support
1

Hi,

I installed asterisk with asterisk repository, and I try to send and receive fax.

but when I use SendFax or ReceiveFax I get following errors:
Could not locate a FAX technology module with capabilities (SEND)
Could not locate a FAX technology module with capabilities (RECEIVE)

please help me.

Which version and which platform?

In any case, I don’t see any fax packages on the asterisk.org repository.

Fax is third party with a non-open source version, with free single connection licence, from Digium and one or two open source options.

asterisk 1.8 on centos 5.5

before I use asterisk repository I use atrpms repository that have asterisk and asterisk-fax
when I switch to asterisk repository and load res_fax module I could use SendFax and ReceiveFax command.
but when try to send or receive a fax following errors happen:
Could not locate a FAX technology module with capabilities (SEND)
Could not locate a FAX technology module with capabilities (RECEIVE)

Do you have res_fax_digium.so loaded, also? You need that in addition to res_fax.so.

Cheers.

thanks Malcolm for your reply,

I load res_fax_digium.so but now I have new errors:
res_fax.c:2184 sendfax_exec: Unable to reserve FAX session
res_fax.c:1689 receivefax_exec: Unable to reserve FAX session

and thanks again for your time

Did you install a license for res_fax_digium?

no I didn’t :frowning:

I thought that is a free module like asterisk-fax in atrpms repository.

thanks malcolm, you saved me a lot of times.
