WAN telnet sessions dropping on Cisco 678 router

I have a Cisco 678 ADSL router that we use to telnet out into remote locations. The remote locations also use the same router to telnet into my site. I can telnet out without ever having any problems and I stay connected as long as I need to. The remote sites use dial-up, cable and DSL to access the internet. All of them have a problem with their telnet sessions into my network dropping. They can stay connected for various amounts of time then it just drops the connection. I would really like to figure out why this is happening and how to correct it. Any ideas appreciated - Thanks!
