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

             Summary: endpoint stasis messages are delivered twice
                 Key: ASTERISK-25137
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25137
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Stasis
    Affects Versions: 13.3.0
            Reporter: Vitezslav Novy
            Severity: Minor


If I subscribe topic ast_endpoint_topic_all_cached I receive all amdpoint messages twice.

In function endpoint_internal_create called from ast_endpoint_create single endpoint topic is created and forwarded to  ast_endpoint_all topic by calling
 
stasis_cp_single_create(ast_endpoint_cache_all(), endpoint->id);

After that same single topic is forwared to tech_topic which is also forwarded to ast_endpoint_all topic. 

Example of resulted topis tree is

SIP/8888 -> SIP -> ast_endpoint_all
SIP/8888 -----------------^

and subscriber who subsribes ast_endpoint_all or higher level topic receives ednpoit messages twice.

I think direct forwarding from single topic to ast_endpoint_all can be deleted from tree (not created at all) and I can prepare patch if somebody comfirms that it is correct way how to fix the problem
