Default [Q] N7105 : Activate native sip in stock rom 4.3 : Possible or not?

Hello,

I have N7105 with 4.3 stock rom (the last french rom : N7105XXUEMK9 - N7105XEFEMK1, thanks sammobile)

My phone is root and I have question : Is it possible to activate native sip account on this rom? (with xposed module for example, or an other manipulation...)

I search on internet (and xda) but didn't found information on this possibility.

Thanks for your help.
