---------------------------------------

             Summary: ConfBridge with name longer than max (32 chars) results in several bridges with same conf_name
                 Key: ASTERISK-23044
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23044
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_confbridge
    Affects Versions: 12.0.0-beta2
            Reporter: Iñaki Cívico
            Severity: Minor


This simple dialplan is used to reproduce issue:

exten => _X.,1,ConfBridge(${confid})

where confid is longer than MAX_CONF_NAME (apps/confbridge/include/confbridge.h)

Each time a call arrives to this point, a new bridge is created with same name (confid truncated to MAX_CONF_NAME length) but different uuid.

In app_confbridge/join_conference_bridge, ao2_find() searches with full conference name (longer than max length). ao2_find result is always null as bridge has a truncated name, then a new bridge is created with the same name.

Behavior is extrange resulting in a several calls connected to the same conf but not earing each other. Here is a console trace:

CLI> confbridge list
