UPDATE: With Ron's help I applied the l2tp command to a VPDN template then applied the template to the VPDN group. Looks like this now. I am wondering which timeout it will use, the template, or the directly configured one that I can't touch. The template I configured with "never".
vpdn-group 1
! Default PPTP VPDN group
accept-dialin
protocol pptp
virtual-template 2
source vpdn-template 2
l2tp tunnel timeout no-session 15
