I have a 2520 configured with 2 dialer interfaces. Dialer3 is configured for a dial up to a remote site, and dialer4 is configured for dial in. The problem is that when I add dialer3 to the dialer pool, dialer 4 doesnt work. Instead I get a debug that the call is rejected because the interface cant bind. If I remove dialer3, dialer4 works fine. Is there a better way to do this, or is my config incorrect?

Do you really need 2 pools?
For a basic config, you could remove the dailer pool-member 2 from the BRI and add Dialer4 to pool 1.
Not sure if that will solve your problem though.
You need to configure PPP authentication on the BRI interface itself. The authentication is needed in order for the dialer interface binding to occur.
i got ur logic of putting dialer 4 also in dialer pool 1.
can u pls tell me then whts the exact reason for putting a dialer interface in different dialer pool ?
you can use different dialer pools when you have multiple physical interfaces, and you want to reserve (or prioritize) some of the interfaces for a specific use.
For example, if you have 8 BRI's that are used for dialin and dialout, but you want 1 BRI to be available for dialout at all times; in this case you put 7 BRI's in pool 1 and pool 2, the last one only in pool 2. Your Dialer profile used for dialin then refers to pool 1, while your dialout Dialer refers to pool 2.
hope this clarifies it a bit,
What would cause the following?
*Mar 1 00:09:08: ISDN BR0:1: Incoming call rejected, unbindable
*Mar 1 00:09:15: ISDN BR0:1: Incoming call rejected, unbindable
In order for the remote user to be able to bind to one of the dilaer interfaces, you will need to issue "dialer remote-name" command.
You have 2 dialer interfaces at the moment, and the router doesn't know which one of the 2 profiles to bind to. Add the dialer remote-name command on both interface, and you should be able to connect.
also try removing on of the pool member, and just use dialer pool-memebr 1 for both dialer profile in conjunction with the dialer remote-name commands on both dialer intefaces.
you have to enter
ppp authentication chap
If the phone rings, and the bri0 gets the call, there is no way to decide for the bri0 to which logical dialer interface the call should be sent.
By enabling the bri0 to read the chap username, it can decide to which logcal interface it sould connect the physical channel from bri0.
