ISDN callin connections

we have a 1721 cisco router. now we have 4 sites (branch offices), that have to call into this router at the same time. 1721 have two WIC-1B-S/T, so there is 4 B channles. (?) Could you give me please right configuration? because my is not working. i don't know, what i do wrong?

Looks like your dialer profiles are missing the dialer remote-name. Without that, we won't know which remote router is supposed to bind to which dialer profile.

Debugs to collect if you get stuck:

conf term service timestamp debug date msec end

debug isdn q931 debug dialer debug ppp negotiation

Cheers,
