Joshua Colp commented on ASTERISK-25137:
----------------------------------------

I think you are correct. For endpoints with a resource they should be forwarded to the tech endpoint topic only. For endpoints without a resource (which is just the technology itself) they should be forwarded to the endpoint all topic.

The other alternative being to just not forward the tech topic to the endpoint all topic.

>          Components: Core/Stasis

> 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
