Spoofing on ISDN line

Setup voice pots on 2811 router last week.  I configured 5 lines and was able to dial in/out.  I came in today and only 3 of 5 phones are able to receive calls.  I've combed thru the logs and can't any issues with the config. Except that the s0/0/0:23 up/up (spoofing)  I have a external CSU and the line is not generating any errors. Any suggestions?
