[Asterisk-Users] ALL incoming Zap channel calls are getting picked up as FAX calls!

[Patrick Cantwell]

All,

	I upgraded my asterisk setup from CVS on or about 12/15.  Suddenly, *all*
of my incoming calls are coming up as FAXes.  I had to disable my fax
extension because every call to my POTS line was getting redirected to my
FAX machine.  After removing the FAX extension, if I call my POTS line from
my cell phone, I get the following:

*CLI>     -- Starting simple switch on 'Zap/1-1'
    -- Executing Answer("Zap/1-1", "") in new stack
    -- Executing Goto("Zap/1-1", "100|1") in new stack
    -- Goto (home,100,1)
    -- Executing Ringing("Zap/1-1", "") in new stack
    -- Executing Dial("Zap/1-1", "SIP/100|30") in new stack
    -- Called 100
    -- SIP/100-5fa2 is ringing
NOTICE[213006]: File chan_zap.c, Line 3545 (zt_read): Fax detected, but no
fax extension
  == Spawn extension (home, 100, 2) exited non-zero on 'Zap/1-1'
    -- Hungup 'Zap/1-1'

I also attempted a call from one of my POTS lines back into the other and
got:

*CLI>     -- Executing ChanIsAvail("SIP/100-e429", "Zap/2") in new stack
    -- Hungup 'Zap/2-1'
    -- Executing Dial("SIP/100-e429", "Zap/2-1/XXXXXXXXXXX") in new stack

I upgraded just now, hoping maybe it was a transient bug.  I recompiled
asterisk and zaptel, this is the version I'm running:

*CLI> show version
Asterisk CVS-12/17/03-15:26:25 built by root at voip on a i686 running Linux
*CLI>

If I re-enable my FAX extension, of course, instead of the NOTICE the calls
just get sent to my FAX machine.
This occurs on both a standard issue verizon POTS line, as well as a
motorola vt1000 telephone adapter provided by vonage.

Does anyone have any idea as to why this may be happening? I haven't changed
anything in my config, just upgraded asterisk and zaptel.

Thanks.
Pat
