Summary:                    [patch] DTMF CallerID detection without polarity
reversal
Description: 
This is related to closed bug 9096, the patch is working fine but there are
some cases where the callerid is not detected due to  DTMFCID timed out
waiting for ring. Exiting simple switch
This happends when I connect a telular base to a TDM400P, convencional
lines has no problems. 
The thing is that the callerid is detected, but it seems to have a problem
detecting the ring after the callerid is setted, sometimes it hangsup the
channel and it starts again a simple switch, this time the channel detects
the ring but it misses the callerid. I have a small fix but maybe this is
not the best way to do it.

  DTMF CallerID detection problems.
  
  The code handling DTMF CallerID drops digits on long CallerID numbers
and
  may timeout waiting for the first ring with shorter numbers.
  
  The DTMF emulation mode was not turned off when processing DTMF
CallerID.
  When the emulation code gets behind in processing the DTMF digits it can
  skip a digit.
  
  For shorter numbers, the timeout may have been too short.  I increased
it
  from 2 seconds to 4 seconds.  Four seconds is a typical time between
rings
  for many countries.
