Cisco 7962 w/ 4 digit extensions doesnt reach *box

Hey guys,

Tried all firmware levels here and currently using 9.4.2SR1. Not even at registration issues yet, whenever I use a 4 digit extension number I dont see anything on my asterisk server. When using a 3 digit I get chan_sip.c:25184 handle_request_invite: Call from ‘’, for some reason its not passing the user name?

Any ideas? Anyone have this working?
