It would be best to configure an appropriate RTP timeout on the gateway. For instance, a if there is no packets after 10 seconds, cancel the call. See your gateway docs on RTP settings. If you need to impose a session length, many gateways support RADIUS auth, and you set a call length parameter in the RADIUS response. With the right sort of RADIUS server, that call length could be dynamically calculated on a per user basis. Tom
