Hello, What is the procedure for adding new fields in some DB table? In particular, I am working under a feature for multiple tcp connections for IPSEC in P-CSCF and for this purpose new fields are needed to store pcscf client and server ports for each registered contact. The new fields 'port_pc', 'port_ps', 't_port_pc' and 't_port_ps' should be added in pcscf.location table. Thank you for your help! -- Best Regards, Aleksandar Yosifov
