[asterisk-users] Asterisk 1.8.7 and ReceiveFAX

Sun Oct 9 11:27:59 CDT 2011

I know for a fact that the f/F option was added in January of 2011 by Kevin. To 1.8 as a patch only.  I was the one that requested it be done.  They told us that they would not include it as part of 1.8.x because it was a new feature. It is in the 10 trunk and seems to work great there. We are running the patch on the 1.8.x release but those servers a few point releases behind as we have not been able to maintain the patch on the current 1.8.x releases. If the f/F option is in the current 1.8.x release it is there against what Kevin told us. I will check the source later today and report back.  

Here is part of the message from Kevin

    It's very possible that future versions of res_fax.c from trunk will not 

    be compatible with Asterisk 1.8.x, so you can't keep doing that forever. 

    However, as long as the version of res_fax.c *compiles* when you drop it 

    into the Asterisk 1.8 tree, it should work.

    Critical changes to res_fax.c (meaning bug fixes or security 

    vulnerability fixes) *will* be made in the 1.8 branch; it's only new 

    features that won't be added there.

Thanks

Well, I tried and it is working in 1.8.7 version, so command 'core show 

application ReceiveFAX' doesn't reflect the real application options, 

only shows c option which is not present in the link sended by Larry. 

Well ...

FYI, I got this error

-- Channel 'SIP/tootaiAUDIO-000000ee' receiving FAX

but the fax was received.

Thanks Larry for the tip.
