Message-summary is for voicemail, not presence. And I’ve seen many phones that don’t have a setting to disable that subscription.
SUBSCRIBE is not required for basic call functionality. If you don’t support it, just remove it. I think that the client is actually correct in that even the first NOTIFY should contain a body. If there is no state to report, the body should be the appropriate indication of that for whatever event is being notified. But there must be something.

It's the only thing that we need from this CPE. p.s.: My apologies for posting logs. 15.09.2017 12:39, Răzvan Crainea пишет: Hi, Alexander! In my opinion, the client does not handle the Notify properly - when the client subscribes, (according to RFC 3842) OpenSIPS must send a NOTIFY with its current state - if he doesn't have any messages, the message body is empty. The client must not reject this message, but accept it and update its current state. Another thing that I noticed is that OpenSIPS lowers the SUBSCRIBE expiration to 600 seconds. Looks like the client ignores this limitation, and doesn't SUBSCRIBE before timeout. That's why after 10 minutes OpenSIPS sends a graceful shutdown NOTIFY with Subscription-State: terminated;reason=timeout. Nevertheless, the SIP client should not stop working, regardless the traffic it received. PS: next time please use an external service such as pastebin.com to post code snippet.

We're using some Chinese GPON CPE with SIP clients in it with OpenSIPS 2.2.3 as a server, and we're having a problem: after successful REGISTER client starts SUBSCRIBE process for event "message-summary", and after authorization pass, server sends NOTIFY with "Event: message-summary", but client respond to it with "SIP/2.0 400 Missing or invalid message-summary" message. On which side is error? In opensips.cfg SUBSCRIBE is handling by this part: _______________________________________________ Users mailing list Users@lists.opensips.org<mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users _______________________________________________ Users mailing list Users@lists.opensips.org<mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users
