[asterisk-users] PRI dialout problem with some numbers...

	I have an Asterisk server (1.4.13) using PRI in Monterrey, Mexico.
This is really the first server I have used with PRI in Mexico as we
normally use MFC/R2.  Everything seems to be working except that some
numbers always seem to be busy when you dial them.  All these numbers
belong to different phone companies.  I know that with R2 this problem
is present if you have a "#define DEFAULT_T1" value under 15000 in
mfcr2.c (the default used to be 5000).  Is there an equivalent value for
PRI?  The company we are using is Alestra.  Here is what I get when we
dial a number that belongs to a company called Protel:

    -- Executing [911070665 at oficina-sup:1] Set("SIP/199-08be6c00",
"TIMEOUT(absolute)=3600") in new stack
    -- Channel will hangup at 2007-11-05 22:03:34 UTC.
    -- Executing [911070665 at oficina-sup:2] Dial("SIP/199-08be6c00",
"Zap/g1/11070665||Ww") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called g1/11070665
    -- Zap/1-1 is proceeding passing it to SIP/199-08be6c00
    -- Channel 0/1, span 1 got hangup request, cause 31
    -- Hungup 'Zap/1-1'
[Nov  5 15:03:34] NOTICE[22300]: cdr.c:434 ast_cdr_free: CDR on channel
'Zap/1-1' not posted
  == Everyone is busy/congested at this time (1:0/0/1)
