cisco 1750 connection timeout problem

[rwatson15425]

Good morning listers,
I have three sites connected via cisco 1750 routers using frame relay. When users connect from the remote site to the central site, the connection stays connected even if there is inactivity. However when a user connects from the central site to the remote site, his connection drops after only a minute or two of inactivity. Where might I begin to fix this problem.

thanks

rick

It'll be good to post the config without any password
