Alarm External Siren/Professional Monitoring

Now you have a UK forum and seem to (hopefully) be paying more attention to the UK market, there are a couple of things that are truly missing from this system. Some sort of external siren/additonal siren I think is essential. I'm lead to believe these are frowned upon in the US but these are common in the UK and you would be hard pushed to find a system that dosen't have one. Either a dedicated unit or even just allowing the camera sirens to be triggered in union with the alarm. I had an alarm event the other day and when I arrived at my house, I couldn't hear it until I had opened the front door. Also the assisted monitoring vs the professional monitoring in the US is night and day. I already get a push notification and an email so the only extra this adds is an automated phone call (and 4G backup which is actually quite useful). I only really find the phone call useful if i'm driving as I won't see the email/notification. Actually having a human being phone you and being able to phone the police on your behalf would be invaluable. Are either of these things currently in the works and be available any time soon? These are the 2 features I feel make this system fall short of the perfect alarm system. Thanks :)
