APPENDIX G SIP Passthrough Enabling/Disabling the SIP ALG You can turn off the WiMAX Device SIP ALG to avoid retranslating the IP address of an existing SIP device that is using STUN. If you want to use STUN with a SIP client device (a SIP phone or IP phone for example) behind the WiMAX Device, use the ip alg disable ALG_SIP command to turn off the SIP ALG. Signaling Session Timeout Most SIP clients have an "expire" mechanism indicating the lifetime of signaling sessions. The SIP UA sends registration packets to the SIP server periodically and keeps the session alive in the WiMAX Device. If the SIP client does not have this mechanism and makes no call during the WiMAX Device SIP timeout default (60 minutes), the WiMAX Device SIP ALG drops any incoming calls after the timeout period. You can use the ip alg siptimeout command to change the timeout value. Audio Session Timeout If no voice packets go through the SIP ALG before the timeout period default (5 minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic and deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation. User's Guide 381
