[asterisk-bugs] [JIRA] (ASTERISK-22116) Bridge API Enhancements: Add the ability to selectively remove bridge feature hooks

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=208090#comment-208090 ] 

Richard Mudgett commented on ASTERISK-22116:
--------------------------------------------

The necessity for this BUGBUG comment is lessened by the ast_bridge_hook_remove_flags enum defined just above the BUGBUG comment.  The bridge_features_remove() (soon to become ast_bridge_features_remove() with the DTMF atxfer work) is available to remove marked classes of hooks.

> Right now, we don't have the ability to choose which feature hook gets removed easily.
> There should be an API call in the Bridging Framework that lets an external user of the framework request that a specific bridging hook be removed.
