According to the RFC, yes:
In addition to being a request to unsubscribe, a SUBSCRIBE message
with "Expires" of 0 also causes a fetch of state; see section
3.3.6.
I'll report a bug. Thanks for your reply.

A subscription with expire:0 should get at least ONE notify, right?
I’ve just that to check the status without setting up a dialog.
It is not invalid. Report this as a bug.

Hello,
I see the following in res_pjsip_pubsub.c:
if (expires_header->ivalue == 0) {
ast_debug(1, "Subscription request from endpoint %s
rejected. Expiration of 0 is invalid\n",
ast_sorcery_object_get_id(endpoint));
pjsip_endpt_respond_stateless(ast_sip_get_pjsip_endpoint(), rdata,
400, NULL, NULL, NULL);
return PJ_TRUE;
}
However, according to RFC 2365, value 0 is perfectly valid, and
should have the effect of ending the subscription.
A natural consequence of this scheme is that a SUBSCRIBE with an
"Expires" of 0 constitutes a request to unsubscribe from an event.
Or is my understanding wrong? Is there some other way to unsubscribe?
Best regards,
Nik
