"488 Not Acceptable Here" tells the peer that the codec(s) offered are not supported. Per the INVITE you are offering G729B. SJPhone only supports G729 with the paid version. Not sure if the paid version will support the g729b though, you would have to check with them.
Try setting your codec to g711ulaw (north america/Japan) or g711alaw (Everywhere else) and see if that works. There is a setting in the SJphone that lists the available codecs listed for use. Check with there support guides.
