I have a very bad sip provider "vbuzzer" but there prices are cheap ,they don't have an app for android (there is one in the store but i am pretty sure it is not official ,and a scam) and their windows software is bad programmed so i was thinking of using another sip software to make the calls for both windows and android phone
when i used x-lite and micro-sip software to make calls i get a voice message telling me that the number is not in service ,luckily in vbuzzer website have an interface showing you the dialed number ,in there i always find that i called 105 while i am in fact calling my number(00+country code+ phone number) !
when i call my number from their software it works fine (but have a lot of other issues like lag)
I don't know what i did wrong so that the sip software will call 105 instead of my number
