Table 85 Configuration > Network > ALG LABEL Enable SIP ALG DESCRIPTION Turn on the SIP ALG to detect SIP traffic and help build SIP sessions through the UAG's NAT. Enable SIP Transformations Select this to have the UAG modify IP addresses and port numbers embedded in the SIP data payload. You do not need to use this if you have a SIP device or server that will modify IP addresses and port numbers embedded in the SIP data payload. Enable Configure SIP Inactivity Timeout Select this option to have the UAG apply SIP media and signaling inactivity time out limits. SIP Media Use this field to set how many seconds (1~86400) the UAG will allow a SIP session to Inactivity Timeout remain idle (without voice traffic) before dropping it. If no voice packets go through the SIP ALG before the timeout period expires, the UAG deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation. UAG715 User's Guide 213
