Thanks for the reply.
Still I am not getting success to call from R1 phones to R4 phones. with only two routers there is no issue.
with 4 routers as u r saying there is no need to configure anything expect IP reachability on R2 and R3, but I think once we configure dial peer on R1 to reach R4 phone and dial peer on R4 to get R1's phones and IP reachability between them.
in this case how R2 will receive calling information and will forward to R3 coz there is nothing configured yet about voice calling information.
IP PHONE----->R1---------------------------------R2---------------------------------R3----------------------------------R4<-----IP PHONE
(1001) (12.0.0.1) (12.0.0.2) (23.0.0.1) (23.0.0.2) (34.0.0.1) (34.0.0.2) (2001)
if we talk about call legs there are total 8 call legs. what about R2 and R3.
I am also puttting configuration here what I have done on R1 and R4.
R1

dial-peer voice 2000 voip
