1. not being in battery saving mode (decreased audio quality)
2. have at least a good Internet connection (good or excellent signal) otherwise weak signal, it’s not great.
3. Nokia updated, Settings > System > System update (Android 8.1.0
4. good service only on the Swisscom fixed and mobile network, without any guarantee on other competing networks.
I have just tested in both directions in SIP and DECT mode, impeccable between Nokia 5 and Swisscom Rousseau 300 DECT
not tested between SIP to SIP
