Anthony Messina commented on ASTERISK-22987:
--------------------------------------------

I do see the same using an Aastra 480i CT, which uses application/dialog-info+xml SUBSCRIBE events.  chan_sip appears to offer some guidance on this in terms of code comments:
{code}
/*! \brief Subscription types that we support. We support
 * - dialoginfo updates (really device status, not dialog info as was the original intent of the standard)
 * - SIMPLE presence used for device status
 * - Voicemail notification subscriptions
 */
static const struct cfsubscription_types {
	enum subscriptiontype type;
	const char * const event;
	const char * const mediatype;
	const char * const text;
} subscription_types[] = {
	{ NONE,		   "-",        "unknown",	             "unknown" },
	/* RFC 4235: SIP Dialog event package */
	{ DIALOG_INFO_XML, "dialog",   "application/dialog-info+xml", "dialog-info+xml" },
	{ CPIM_PIDF_XML,   "presence", "application/cpim-pidf+xml",   "cpim-pidf+xml" },  /* RFC 3863 */
	{ PIDF_XML,        "presence", "application/pidf+xml",        "pidf+xml" },       /* RFC 3863 */
	{ XPIDF_XML,       "presence", "application/xpidf+xml",       "xpidf+xml" },       /* Pre-RFC 3863 with MS additions */
	{ MWI_NOTIFICATION,	"message-summary", "application/simple-message-summary", "mwi" } /* RFC 3842: Mailbox notification */
};
{code}

> When trying to subscribe to BLF events I get the following warning:
> WARNING[31048]: res_pjsip_pubsub.c:786 pubsub_on_rx_subscribe_request: No registered subscribe handler for event dialog
> Hints are setup. I believe I recall talking to someone earlier in the IRC about this and they said it needed to be built out in v12.
