Nokia 515 Dual SIM + VoIP

Posted:Sun 26 of Nov, 2017 (22:14 UTC)
Phone Nokia 515 dual SIM https://www.gsmarena.com/nokia_515-5663.php
Platform Series 40 https://en.wikipedia.org/wiki/Series_40
I set up the voip setting correctly. SIM1 card is a 3G internet card, SIM2 card is a card designed for voice calls. No problem connecting to my SIP account. But when connected to a SIP account, the SIM2 card is turned off. To re-enable SIM2, I have to deactivate the mobile data.
Does the nokia 515 dual SIM support simultaneous VoIP and traditional voice calls via GSM? If so - how to make SIM2 active when connected to a SIP account?
My settings:
call type settings -> Prefer net call
Software version 10.34 13-03-14 RM-952
