Got it btw, had to make a structure...

using System;
using System.Runtime.InteropServices;

public class clsNotification
{
    private enum SoundEvent
    {
        All = 0,
        RingLine1,
        RingLine2,
        KnownCallerLine1,
        RoamingLine1,
        RingVoip
    }

    private enum SoundType
    { 
        On = 0,
        File = 1,
        Vibrate = 2,
        None = 3
    }

    private struct SNDFILEINFO
    {
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
        public string szPathNameNative;

        [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
        public string szDisplayNameNative;
        
        public SoundType SstType;
    }
    
    [DllImport("aygshell.dll", SetLastError = true)]
    private static extern uint SndSetSound(SoundEvent seSoundEvent, ref SNDFILEINFO pSoundFileInfo, bool fSuppressUI);

    [DllImport("aygshell.dll", SetLastError = true)]
    private static extern uint SndGetSound(SoundEvent seSoundEvent, ref SNDFILEINFO pSoundFileInfo);

    public int SetRingerVibrate()
    {
        SNDFILEINFO sfi = new SNDFILEINFO();
        sfi.SstType = SoundType.Vibrate;
        uint ret = SndSetSound(SoundEvent.All, ref sfi, true);
        if (ret != 0)
        {
            return 1;
        }
        return 0;
    }

    public int SetRingerOff()
    {
        SNDFILEINFO sfi = new SNDFILEINFO();
        sfi.SstType = SoundType.None;
        uint ret = SndSetSound(SoundEvent.All, ref sfi, true);
        if(ret != 0)
        {
            return 1;
        }
        return 0;
    }

    public int SetRingerOn()
    {
        SNDFILEINFO sfi = new SNDFILEINFO();
        sfi.SstType = SoundType.On;
        uint ret = SndSetSound(SoundEvent.All, ref sfi, true);
        if(ret != 0)
        {
            return 1;
        }
        return 0;
    }

    private SNDFILEINFO mOldSoundFileInfo = new SNDFILEINFO();
    public int SaveSound()
    {
        uint ret = SndGetSound(SoundEvent.All, ref mOldSoundFileInfo);
        if(ret != 0)
        {
            return 1;
        }
        return 0;
    }

    public int RestoreSound()
    {
        uint ret = SndSetSound(SoundEvent.All, ref mOldSoundFileInfo, true);
        if(ret != 0)
        {
            return 1;
        }
        return 0;
    }
}
