look here they changed CID thing, http://www.nonoh.net/en/did.ht

受你们的启发，我也试着改变CID，结果最坏的事情发生了，我原来的CID可以正确的显示CID。但想改到GV，结果旧的Softphone不工作，They ask you update, then the new updated version,showing CID is locked.
they give you a oage ask you use another service to have DID, certainly they want rape you!
I can setup my original CID settings, but do not work anymore, they do not give you this option.
