Hello folks - I'm one of the engineers that has been working specifically on the issue with no video over AT&T.  This has been a difficult one to work out. We’ve been working closely with AT&T and have determined that the issue is due to a configuration issue on AT&T's network. Since then, we've been working to find a workaround for this, and we believe that we have found a solution. It's testing well internally, but we would like to know how it does in the wild. I’m reaching out to affected sites to see if they would be able to perform some testing of this new solution.
 
To test this out, you’ll need to install a new build of our iOS app – this is currently iOS only – and place some intercom calls while using both the cellular and wifi connections of the device. Ideally, place the calls using only cellular, then again with the wifi enabled. You can place the calls either from the mobile device, or from another device to the mobile. Please leave the app open while running these tests.
Please send me a message here if you're interested in testing this out, and I can provide you with more information. Let me know what carrier you're using when you message me. As the issue is showing up mostly on AT&T, testers there would be great, but if you're seeing this on other carriers as well, we'd like to see if this new build addresses those carriers as well. (@olichops, I'd be curious to see if this addresses the wifi issue you mentioned as well.)

Thanks for the report folks - we've been able to dupe this one, and have a bug report written up (CI-22531). It's being worked on.

The 4KB limit is for the entire payload of the push. There's additional information being included in addition to the message content that will chew up some of the data available. Not quite 4KB, but there's some extra data in there the app uses. I haven't found any info about current caps, or if they can be increased. (I can't really make any promises about if/when that would increase either.) I'll see what I can do.

I'm not sure about the size limits on the C4 side, I'd have to ask around. However, on the Apple/iOS side, there's a limit of 4KB for standard push notifications, and 5KB for VoIP pushes. (VoIP pushes are used for intercom calls only, btw.)

@South Africa C4 user - Quick update for you - there was a new limit implemented of 914 characters a while back. (There's also a timestamp that is appended that pushes things up to a total of 1,000 characters, which is where the 914 value comes from.)
The bug is still open, so the limit may be removed, but I don't have a timeline for that. However, I wanted to share the limit so that you could at least have a target to aim for to get some emails going back out.

@South Africa C4 user - One more update - the limit has been increased to 1,000,000 characters. Not that you necessarily want to send an email that big, but it's at least a little bit more than 914.  I can't give an exact date for the rollout of the new limit, but it's on the way.

Thanks for the report folks - I've just logged a bug on this for the iOS team. (CI-20607)

Don't have specifics to share, but we will be looking into ways to better monitor this and raise an alert if needed.

Done. If I receive an update, I'll post up here.
