I am a MyNetFone user. HOW do I apply my PORTED NUMBER to ZoiPER for MAC settings.

Question

Apply  PORTED NUMBERS to ZoiPER for MAC settings

MyNetFone has unusual numbers, and even so, I ported my number from Engin.

I have been through their guide as to DOWNLOAD and INSTALL ZoiPer for MAC.

I do not know if my PORTED number needs to be applied to the SETTINGS, or WHERE I can do that. 

Q: HOW do I APPLY my PORTED NUBER to ZoiPER for MAC? 

With thanks,
