Hi all, I've noticed that certain modules will register methods with the pjsip endpoint that subsequently end up in the Allow header which can be queried from it, for example to be used in response to a OPTIONS request. The evsub module will register SUBSCRIBE and NOTIFY, while the publishc module will register PUBLISH. I was just wondering if this is in fact correct behaviour. I'm not at all certain about the semantics of the Allow header, but it tend to think that this header includes any methods that the endpoint will successfully process if sent to it. Now the evsub module in this case allows for UAS sessions to be created, but I think the publishc module is only a client and does not allow for processing of incoming PUBLISH requests. Can anyone on this list confirm or deny that the Allow header works in this way and expand on what the correct behaviour is in this case. Just to be clear I want to implement a UA that does not handle SUBSCRIBE requests, but can send SUBSCRIBE requests to an agent. Ruud Klaver AG Projects
