In case the user agent crashes during a PSTN call. That is, to send a "safety" BYE after X minutes after an INVITE
Well, SER would have to spoof the BYE that would normally come from the UA. This probably isn't the best way to do this. Plus, you might disconnect an actual call.
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.
