[svn-commits] sruffell: branch 1.4 r4491 - in /branches/1.4/kernel: zaptel.h zttranscode.c

[SVN commits to the Digium repositories]

Author: sruffell
Date: Tue Aug 19 15:14:25 2008
New Revision: 4491

URL: http://svn.digium.com/view/zaptel?view=rev&rev=4491
Log:
Couple of fixes for the transcoder:

- In dahdi_transcode.c,  Embed the identifiation number, assigned sequentially
  when the transcoders are registered, in the transcoder structure. This allows
  DAHDI_TC_GETINFO to work as expected even though the transcoders are rotated
  on the list in order to spread the load. 

- In wctc4xxp, fix bug where all transcoders are named tc400b0.
