1 Unfound users are not processed ping status

sip_user_status.status = ping_status;
	sip_user_status.status_len = sizeof(ping_status);
	sip_user_status.contact = sip_contact;
	sip_user_status.contact_len = sizeof(sip_contact);
	sql = switch_mprintf("select ping_status, ping_count, contact from sip_registrations where sip_user='%q' and sip_host='%q' and call_id='%q'",
			     sip->sip_to->a_url->url_user, sip->sip_to->a_url->url_host, call_id);
	sofia_glue_execute_sql_callback(profile, profile->ireg_mutex, sql, sofia_sip_user_status_callback, &sip_user_status);
	switch_safe_free(sql);

If the user is not found, sip_user_status.count is an uninitialized value.

2 Make SOFIA_REG_UNREACHABLE SOFIA_REG_REACHABLE name and description consistent.

typedef enum {
SOFIA_REG_REACHABLE,
SOFIA_REG_UNREACHABLE,

   SOFIA_REG_INVALID

} sofia_sip_user_status_t;

const char *sofia_sip_user_status_name(sofia_sip_user_status_t status)
{
static const char *status_names[] = { "UNREACHABLE", "REACHABLE", NULL };

if (status < SOFIA_REG_INVALID) {
	return status_names[status];
} else {
	return "INVALID";
}

}
