I'm the one who posted re Grandstream gateways using the To-URI rather than the Request-URI in the invite message. I've filed a support request with Grandstream seeking confirmation/resolution but I have limited expectations.
I suspect you may be seeing the same problem. In the meantime, you may be able to use the dialplan (and its limited transformation funtionality) in the gateway to manipulate the To-URI to your needs. This is what I wound up having to do.
