default
Sets the P-CSCF discovery to default parameter.
no
Removes/deletes configured parameters for P-CSCF discovery.
table { 1 | 2 }
Specifies that which P-CSCF table is to be used to obtain the primary and secondary P-CSCF addresses. Total
2 tables can be configured for P-CSCF discovery.
2 tables can be configured for P-CSCF discovery.
algorithm { ip-address-modulus | msisdn-modulus | round-robin }
Specifies the algorithm to select the row from the P-CSCF table to be used for P-CSCF discovery.
• ip-address-modulus: This algorithm divides the IP address, in binary, of the subscriber by the number
of rows in the table, and the remainder is used as an index into the specified table to select the row.
• msisdn-modulus: This algorithm divides the MSISDN value, in binary without the leading "+", of the
subscriber by the number of rows in the table, and the remainder is used as an index in the specific table
to select the row.
to select the row.
• round-robin: This algorithm rotates all rows in the active table for selection of the row in round-robin
way. If no algorithm is specified this is the default behavior.
