Brain strain please help!!!!!

I have this SER – MYSQL –SERWEB

When I place setflag(3) or setflag(1)

Example:

setflag(3);

acc_db_request("Missed Call", "missed_calls");

I note when I place a call to a user that is not online the missed_calls table is populated with:

| "8838212361" <sip:8838212361@***.***.***.***>;tag=SxCH3s2YXJCUGNdq | "8838212349" <sip:8838212349@***.***.***.***> | Missed Call | INVITE | sip:8838212349@***.***.***.***| sip:8838212349@***.***.***.***| sip:8838212361@***.***.***.***| sip:8838212349@***.***.***.***| waLKvXL2KBr8oAuS@***.***.***.*** | n/a | n/a | SxCH3s2YXJCUGNdq | n/a | 2005-05-18 07:06:08 | 2005-05-18 17:06:08 |

The two n/a are columns username & domain . When I log in as the user in ser web the missed the call the data does not display. I figure this is because of the fields n/a. Anyone have any ideas on what I have done wrong

I have checked the table in mysql and noted the fields are set to “not null” this should mean that the fields are never empty, were does the n/a come from and why did the fields not populate with the correct data?
