Hi Group,
 
No matter it is dialer-watch or demand-circuit, I always find that the remote router (ip5) will disconnect the call about 30 sec everytime when ip2 call ip5. Which parameter in ip5 affect this value? I suppose it should be dialer idle-timeout, but it is not. During the lab, should I modify the parameter (which one), otherwise the isdn will also up/down frequently. Thanks.
 
Router ip5
interface BRI0/0
 ip address 172.16.12.5 255.255.255.0
 encapsulation ppp
 dialer idle-timeout 500
 dialer enable-timeout 2
 dialer map ip 172.16.12.2 name ip2 class dialer1 broadcast 4082222222
 dialer callback-secure
 dialer-group 1
 isdn switch-type basic-ni
 isdn spid1 40811111111 4081111111
 no cdp enable
 ppp callback accept
 ppp authentication chap
end

Router ip2
interface BRI0/0
 ip address 172.16.12.2 255.255.255.0
 encapsulation ppp
 ip ospf demand-circuit
 dialer idle-timeout 30
 dialer map ip 172.16.12.5 name ip5 broadcast 4081111111
 dialer-group 1
 isdn switch-type basic-ni
 isdn spid1 40822222221 4082222222
 no cdp enable
 ppp callback request
 ppp authentication chap
end
