Section 4.4.2 says:

set KeepaliveTimer(S,G) to RP_Keepalive_Period;

It should say:

set KeepaliveTimer(S,G) to max(Keepalive_Period, RP_Keepalive_Period);

Notes:

The normal keepalive period for the KAT(S,G) defaults to 210 seconds. However, at the RP, the keepalive period must be at least the Register_Suppression_Time, or the RP may time out the (S,G) state before the next Null-Register arrives. Thus, the KAT(S,G) is set to max(Keepalive_Period, RP_Keepalive_Period) when a Register-Stop is sent.
