ISDN disconnects too soon

[1100466]

hi all,

i've got a problem,

i have two cisco routers (one Cisco 1720 & one Cisco 801) connected to eachother through ISDN.
The dialer idle-timeout is set at 60 sec., but mine ISDN-connection doesn't last so long. it's disconnected after 20 sec.

i've already upgraded the IOS from the 801....do i have to upgrade also the IOS from the 1720?

because i don't know what the do know...

What side does the drop seem to be comming from? Are you using the same ISDN provider at both end? Does your provider have a timer set on idel activity?
