[Asterisk-Users] Testing asterisk faxing functionality

[patryk]

I have asterisk with rxfax txfax modules.I want
to test fax sendig and reciving in one asterisk
instance, in extensions.conf I have :

exten => 1234567,1,rxfax(/home/patryk/fax-new.tif|debug)

exten => s,1,Dial(1234567)
exten => s,2,txfax(/home/patryk/fax.tif|caller|debug)

but I doesn't seem to work.But when I'm calling on this number I can
hear fax tones.
I can't find sip client with fax fuctionality for linux I think it would
help with testing.
