Is Block CID Setting set to "No" in your WRTP54G?
Voice-->Line 1-->Supplementary Service Subscription-->Block CID serv
Try changing to "No."
Do you have your name specified under Voice-->Line 1--> Subscriber Information--> "Display Name" in your WRTP54G?
Make sure you're using "Advanced view."
I'm having trouble finding an online WRTP54G emulator where I can actually see relevant Voice information.
