[asterisk-dev] DAHDI-Linux 2.6.0-rc1 and DAHDI-Tools 2.6.0-rc1 Released

Asterisk Development Team asteriskteam at digium.com
Thu Nov 3 16:55:28 CDT 2011

The Asterisk Development Team is pleased to announce the first
release candidate for DAHDI-Linux 2.6.0 and DAHDI-Tools 2.6.0

2.6.0 is a feature release which:

  - Adds support for the TE820 8-span card to the wct4xxp driver.

  - Decrease load time of analog cards supported by the wctdm24xxp

  - Adds sysfs object model to facilitate persistent span numbering
    and early loading of modules (NOTE: by default this release
    still behaves like previous releases with regards to span
    numbering assignment).

  - dahdi_pcap tool is now included in DAHDI-tools but not compiled
    by default since it depends on a currently unsupported interface
    in DAHDI-Linux. It is intended that in future releases this will
    be compiled by default.

Issues closed in this release candidate:
DAHTOOL-49: adding pcap support to Dahdi
            (Reported by: Torrey Searle)
DAHLIN-258: weird sound with a native bridged isdn-bri connection
   	    (Reported by: Daniel)

DAHDI-Linux 2.6.0-rc1, DAHDI-Tools 2.6.0-rc1, and DAHDI-Linux-Complete
2.6.0-rc1+2.6.0-rc1 are available for immediate download at:
