J179 phones are showing "Acquiring Services" after certificate was regenerated

[PhonesTech]

Hi guys, we've ran into this issue with different clients where if we re-generate the certificate in IP office (Multiple versions of 11.0 and 11.1), the phones stop working after a day or two or after a reboot. The phones screen shows acquiting services and only way to get them working again is by resetting the phone. My question is what's the best way to regenerate the certificate, without any interruption.

You should use a certificate authority that generates the certificates and avoid using the self signed certificates from IPO security settings.
