Summary:                    [patch] Asterisk 1.6.0-rc6 crashes with ReceiveFAX
Description: 
I'm trying to receive a fax message sent by Zoiper 2.16. Following
instructions on webapges I have edited the follwoing configuratin files:

===SIP.CONF=== 
[general]
t38pt_udptl = yes

[1000]
type=friend
context=fax_context
host=dynamic
allow=all
t38pt_udptl = yes


===EXTENSIONS.CONF===
[fax_context]
exten => 300,1,Verbose(Receiving....)
exten => 300,n,ReceiveFAX(fax.sff)
exten => 300,n,Hangup()

exten => h,1,Verbose(Received)
exten => h,n,Noop(FAXSTATUS = ${FAXSTATUS})


Unfortunatelly, when I try to send a fex asterisk crashes completely: i
need to strat it again by typing "sodo asterisk" and then "sodo asterisk
-r" to enter the console.

On the asterisk console I have only following information

Connected to Asterisk 1.6.0-rc6 currently running on durotar (pid =
15529)

SpanDSP 0.0.5pre4 works fine.
I bet you guys have multiple versions of SpanDSP installed on your
machines possibly at different locations. So you can compile fine with one
of them while actual loading of library picks up another one (old) and
Asterisk crashes - just type

locate libspandsp.so

and see what directories in addition to /usr/local/lib and the directory
where spandsp was built contains it.

I personally would remove all instances of spandsp libraries before
installing new. Something like

rm /lib/libspandsp* /usr/lib/libspandsp* /usr/local/lib/libspandsp*

USE AT YOUR OWN RISK!
