Summary:                    [patch] I could not find an easy way to access 
DAHDI channel and span number from the dialplan.
Description: 
  I could not find an easy way to access from the dialplan the span and the
PRI channel being used by an Asterisk channel. As a quick solution I
patched chan_dahdi so that it will populate - if applicable - two
variables:

  PRI_CHANNEL: the PRI channel number
  PRI_SPAN: the PRI span number

  These variables can then be used in the dialplan. The patch it's pretty
simple, even if I don't know how much it could be needed by others.

---------------------------------------------------------------------- 
I see the point, the attached patch will add two variables that can be read
using the CHANNEL() function. 

Now it's possible to access the span and PRI channel information using:

  CHANNEL(pri_span)

and

  CHANNEL(pri_channel)

Sorry for the previous patch, I guess I should have asked how it would
have been the proper way of handling this.
