Syntax
Sets the P-CSCF discovery to default parameter.
Removes/deletes configured parameters for P-CSCF discovery.
This keyword 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.

Default: round-robin.
This option enables the table number and algorithm specified by the
configuration in Policy Control Configuration mode.
If the primary host in that configuration is down it assumes that the primary P-CSCF in the row of P-CSCF
table is also down, and it does not return that IP address in the create PDP context response.
This option also performs the deactivation processing of the PDP contexts when Diameter Policy Control
Application (DPCA) switches, host tables as detailed in the
