Use inactivity-timeout to have the ZyWALL / USG apply SIP media and
signaling inactivity time out limits.
Use media-timeout and a number of seconds (1~86400) for how long to
allow a voice session to remain idle (without voice traffic) before dropping
it.
Use signal-timeout and a number of seconds (1~86400) for how long to
allow a SIP signaling session to remain idle (without SIP packets) before
dropping it.

than 21.
Use signal-extra-port with a listening port number (1025 to 65535) if
you are also using H.323 or FTP on an additional TCP port number, enter it
