I have a problem
 

I have a problem. I Register to sipbroker.com - Member No. 340219.
In Member Details edit fields Userid from 331@vinety.us.to to
331@apbx.us.to, but the system does not edit the existing record. The
system added another new record, and obtain duplicate records.
*10060 vinety.us.to
*10061 apbx.us.to
Is it possible to edit (delete) a record?
When editing how to stop adding new records?

Thanks in advance.
