The dialer-watch method should work fine with your requirements. We need to know what the PSTN links (analog or isdn) went down and re-dials. "debug dialer" will show us the reason for that.
Dialer-watch should not keep the pstn link up regardless of inetresting traffic and even if the idle-timeout expires. It will only bring down the backup link is the watched route learned via primary link.
For the second point, what I Learned is , when I define the router to be watched is the defalut route ( 0.0.0.0/ 0.0.0.0 ) and do not want to run routing prorocol over the backup link I have the following defalut rotute defind;
ip route 0.0.0.0 0.0.0.0 172.16.50.2 150
When the router powers up, if the promary link is down, when I query teh route table I can see the floating static defalut route has been installed irrespective of the backup link UP/DOWN as follows;
172.16.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.16.150.0/24 is directly connected, FastEthernet0
C 172.16.200.0/30 is directly connected, Loopback1
C 172.16.50.0/30 is directly connected, Async5
S* 0.0.0.0/0 [150/0] via 172.16.50.2
Therefore , I bilieve that the router "thinks" that the route to be watched, now via the static route , as the PRIMARY link.
Since dialer watch assumes that the "PRIMARY" link is UP, it is never going to dial.
