We're running CUCM System version: 10.5.2.12901-1. Last night we applied a device pack (cmterm-devicepack10.5.2.14068-1.cop.sgn) and rebooted all cluster nodes. Phone firmware's did not change. Models are 8841 and 8861.
Today the phones are working fine, but the font has noticeably changed on the display. It's a bit larger. Several users have reported this.
What could change a font change on the phone display? Is it something unrelated to the devicepack that took affect during the reboot? Or the devicepack itself?
No, sorry. The packages contained newer firmwares. But we overrode the firmware upgrade via Device Defaults, to keep it at the original version. Also confirmed via GUI after the upgrade that the phones did not upgrade. They were (and are still) running sip88xx.10-3-1-20.
