Manage the Application Level Gateway for SIP Sessions

support for multiple SIP clients. SIP support for the ALG, which is an IPv4 feature, is disabled
by default.

Description
This is a nonconfigurable counter that displays the total number of dropped packets
when the session limit is reached.
For each protocol, specify a time-out in seconds. A session expires if no data for
the session is received for the duration of the time-out period. The default time-out
periods are 1800 seconds for TCP sessions, 120 seconds for UDP sessions, and
60 seconds for ICMP sessions.
