Looks like my problem is described in the NUA documentation:
sending a SUBSCRIBE with Event: header and two Accept: headers:
nua_subscribe(nh,
SIPTAG_EVENT_STR("presence"),
SIPTAG_ACCEPT(accept1),
SIPTAG_ACCEPT(accept2),
TAG_END());
fetching tag values when processing nua_r_subscribe event:
sip_accept_t *ac = NULL;
sip_event_t *o = NULL;
tl_gets(tl,
SIPTAG_EVENT_REF(o), /* _REF takes a reference! */
SIPTAG_ACCEPT_REF(ac),
TAG_END());
Problem is: o is still NULL afterwards.
This is my call to nua_subscribe:
nua_subscribe(op->op_handle,
NUTAG_URL((url_t*)extended_uri.c_str()), // added by JVDB
SIPTAG_FROM_STR(ssc->cose_address),
SIPTAG_EXPIRES(exp),
SIPTAG_EVENT_STR(event),
TAG_END());
event is set to "presence".
