asterisk users - May 2011 - ConfBridge - Failed to find a bridge technology to satisfy capabilities

Hi,

I am trying to use ConfBridge application, but it throws "Failed to
find a bridge technology to satisfy capabilities 0x4 (ulaw)" error.
Please see console output below.

    -- Executing [501 at services:9]
ConfBridge("SIP/OpenSER-00000005",
"1001") in new stack
[May 19 13:36:05] DEBUG[7452]: app_confbridge.c:404

[May 19 13:36:05] ERROR[7452]: app_confbridge.c:435
join_conference_bridge: Conference bridge '1001' could not be created.


Could someone please let me know what is required to make it work?

Regards,
Chris

What version of Asterisk are you using?  ConfBridge was rewritten in 
trunk and would be good to see if you have the same issue.

Hi Paul,

I am using 1.8.4. Just tried with the latest trunk (SVN-trunk-r319661)
and it still doesn't work, this time throwing error as below:

    -- Executing [501 at services:3]
ConfBridge("SIP/OpenSER-00000001",
"10001") in new stack
[May 19 16:11:58] DEBUG[30778]: app_confbridge.c:775

join_conference_bridge: Conference bridge '10001' could not be
created.

I wonder if this recent commit to the 1.8 branch would help fix this issue at
least with 1.8.

  Log:
  Revert part of a change to the bridging API code

  The capabilities used in the bridging API are very different than the
  ones used for formats. When the conversion was made expanding the bit
  width of codecs, the bridging code was accidentally accosted in ways
  that it didn't deserve.

  Modified:
      branches/1.8/include/asterisk/bridging.h
      branches/1.8/include/asterisk/bridging_technology.h
      branches/1.8/main/bridging.c

As far as why svn trunk is stating that it cannot create the bridge, the debug
message is not very informative as to why it couldn't create the conference
bridge from what I could see briefly looking at the debug logs you posted in
another message.

Just as a note, the versions of ConfBridge in 1.8 and Trunk are completely
different.  Trunk will likely give you much better results.  In 1.8 ConfBridge
is more of just an experimental exercise of the bridging API.

Thanks! Indeed I was missing bridge_softmix.so module. Once added to
modules.conf ConfBride works as expected :)
