Hi! I have a scenario where a presence agents only performs registration (otherwise the SBC does not allow messages from this client) and sends PUBLISH requests.
Thus, this SIP client only sends REGISTER and PUBLISH, and is not willing to accept any SIP requests. Thus, I wonder if it is correct to signal an empty Allow header Allow: in the REGISTER request to avoid incoming methods. According to ABNF it should be allowed. So is this the preferred way or is there a better choice? thanks Klaus _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
