We have 25 MR52 access points running on MR 25.14.
Signal becomes less than 20 dB for affected clients. After disconnecting & re-connecting the signal becomes normal.
Client balancing is on
Channel utilization becomes jammed most of the time for both 2.4 & 5 GHz.After rebooting it becomes normal.
Aggregation is enabled, running on 2 Gb, with one POE enabled port
AP's are not running on low power
Generally there's no impact but users are definitely facing voice quality issues
Could you give us more informations about your clients ? (Smartphones, laptops ? Which model ? Quantities ?)
What you're relating here seems to be linked with roaming issues (still connected on a far away AP, even if there's another one with better signal available. The action to disconnect/reconnect is kind of forcing the new connection on the nearest AP)
I suppose you're talking about a VoWiFi environment ?
I would suggest first to test :
- Raising the minimum bitrate of your SSID (the value should depend on your clients 802.11 oldest compatibility)
This would influence a bit the roaming decision from the client
- Disabling the client balancing (except if you have A LOT of active clients)
This functionality is sometimes misinterpreted by clients and behaviours could be affected
- Forcing your channel width to 20MHz
This should influence the available airtime thus making your channels less jammed
Furthermore, I'd look into setting up 802.11r & 802.11k standards, but not as a first pick here

ps. VoIP over WiFi is always painfull because you don't have control over the RF. It can run great for six months, and then someone shifts in next door, upgrades their WiFi upstairs, etc, and your VoIP over WiFi degrades - completely outside of your control. Often you can't fix it - apart from putting in more and more APs. And then sometimes the VoIP devices don't roam properly and you get another wave of issues.
