Hello Ariujn,
you can use the file in attachment that shows the usage of dialer pools and dialer interfaces.
notes:
you need to verify the ISDN switch type on each side with the provider.
it is very important to define what is the interesting traffic that can trigger a call and can keep the link up.
Failing to do this leads to high bills to be payed
BRI requires a slightly different configuration but it can use the dialer profiles.
Hope to help
Giuseppe
