I have one PRI line at india and one BRI line at the US.
We are able to connect from india to US. But when we try to call from US to India PRi number, We are getting the bellow error.
the show isdn active is not showing remote hostname (in either router).
PPP LCP negotiation itself not getting completed.

Look at 'show isdn status'. If layer2 does show MULTIPLE_FRAME_ESTABLISHED or stay in that state then get 'debug isdn q921'. For example, try doing a 'shut,no shut' on the interface.

Hi Prasath,
Same configuraions work just fine for me ,make sure you dont have any access list enabled on the US end .Try adding dialer-list 1 protocol ip permit in global config mode & dialer map ip x.x.x.x name test 01191xxxxx (this should be the phone no of the other end)
Try to ping the pri interface ip to bring up the session .
if any issues send the debugs ppp negotiation out put of both side

Thaks for the comments,
Just recently the US telco updated that there could be a possible compression issue at switch side. I will update once i hear from them
