Hi,

sig-part-b#sh run int s2/0:15

Building configuration...

Current configuration : 453 bytes

!

interface Serial2/0:15

no ip address

encapsulation ppp

ip mroute-cache

dialer pool-member 1 max-link 2

dialer pool-member 2 max-link 1

dialer pool-member 3 max-link 1

dialer pool-member 4 max-link 1

dialer pool-member 5 max-link 2

dialer pool-member 6 max-link 1

dialer pool-member 7 max-link 1

dialer pool-member 8 max-link 1

dialer pool-member 9 max-link 1

isdn switch-type primary-net5

no cdp enable

ppp authentication chap

ppp multilink

end

sig-part-b#sh run int dial9

Building configuration...

Current configuration : 278 bytes

!

interface Dialer9

description *** Backup Prisme ***

ip address 10.203.205.29 255.255.255.252

dialer remote-name prisme-b

dialer idle-timeout 55

dialer string 0499581013

dialer hold-queue 15

end

And This one on a Branch :

interface BRI0

description *** Backup ISDN sig-part-b int dialer 9 ***

no ip directed-broadcast

dialer map ip 10.203.205.29 name sig-part-b broadcast 0248689930

dialer hold-queue 15

dialer-group 1

isdn switch-type vn3

no fair-queue

ppp authentication chap

For a lot of other routers there's no problem with the same definition of Dialer Profile. With the int Dialer 9 it runs ONLY when I put off the "max-link 1" option in the dialer-pool member command. D'you know why ?? Thanks

PPP is not running for this Dialer 9.

Below the error log (deb is q931) :

Re: Pb with Dialer Profile (dialer pool-member 9 max-link 1)

First, not sure why do you have configured "dialer-string 0499581013" under interface dialer 9. You don't need to if central router just receives the call.

Anyway just turned on "debug dialer" to see any possible dialer issues including max links..So enable following debug and after that let the call come in and fail.

debug isdn q931

debug dialer

debug ppp nego

debug ppp auth

You can use "dialer max-call x" or "dialer max-link x" command under interface dialer 9 to limit number of calls.
