RE: KX-NS 700 can not access to SIP trunk

Have you locked down the port 5060 to your sip provider. You could be getting bombarded by unwanted sip requests Have you done a trace on the sip

Have you co keys on the phone to see if light are all on

After that it could bee a faulty card, but I yet to get one
