[asterisk-users] Asterisk, SpanDSP and RXFax

[Darren Nay]

Hey All,

 

I am attempting to get the RXFax app working and having a hell of a time
of it.  I am hoping that some of you fine folks can help me out. 

 

I have installed Asterisk v1.2.14, SpanDSP v0.0.2pre26 and app_rxfax.
All compiled and installed fine.

 

When I attempt to call the extension I have created for receiving fax's
then I get the following error once just as the rxfax application is
invoked:

Jan 16 09:29:11 NOTICE[5414]: channel.c:1950 ast_read: Dropping
incompatible voice frame on SIP/192.168.2.250-b3203b30 of format slin
since our native format has changed to ulaw

 

Strange thing is that after that error Asterisk will sit and wait for
the FAX to complete:

Executing Application: (rxfax) Options: (/tmp/11689649465416/fax.tiff)

 

When the fax is completed then the sending fax machine always says that
the fax was sent successfully, but Asterisk errors out of the rxfax
application and never writes the fax.tiff file.

 

Has anyone seen this behavior before?  Any help that you could provide
would be very much appreciated.

 

Thanks in advance!
