Summary:                    Asterisk 1.6 restarts after completion of incoming
fax
Description: 
Asterisk 1.6.0.3rc1
dahdi-linux-2.1.0
dahdi-tools-2.1.0
libpri-1.4.8
SpanDSP-0.0.5pre4

My configuration is as follows. I have an asterisk 1.4 server that
interfaces with a POTS network. Our fax calls come into this server on an
analog card. The extension is then passed onto a second server running 1.6
which is dedicated for faxes. here is the extensions.conf

exten => _22X,1,Wait(2)
exten => _22X,n,Set(FAXFILE=/var/fax/${UNIQUEID}.tif)
exten => _22X,n,Answer()
exten => _22X,1,Wait(3)
exten => _22X,n,ReceiveFax(${FAXFILE})
exten => _22X,1,Hangup()

The fax is saved in the correct directory. However, after the save
asterisk restarts with a code 127

the only error that shows up is:

 symbol lookup error /var/lib/asterisk/modules/app_fax.so undefined symbol
T30_get_tx_ident 

A fresh reinstall of everything did not fix the problem.

When it was first installed everything work great. When I stress tested
with 8 incoming faxes simultaneously this problem popped up and never went
away.

---------------------------------------------------------------------- 
here is what I found. The variables in app_fax.c 

local_ident = T30_get_tx_ident(f)
far_ident = T30_get_rx_ident(f)

these values hold no value. The code will compile but asterisk will end
with a code 127 and restart after the completion of any incoming fax. 

local_ident = NULL
far_ident = NULL

'seems' to have fixed the problem, recompile and reinstall asterisk for
the fix to take effect. I will be stress testing this configuration and I
will let you guys know how it goes.
