Hello Ashish,
some more information is needed in order to get better help.
Some questions:
1) what type of ISDN access are you using ?
BRI or PRI I suppose BRI is more likely available for a 876.
2) what ISDN switch type have you configured ?
3) what type of call are you meaning ?
I suppose a voice call but ISDN can be used for data with DDR so specify it.
4) may you post a filtered version of your configuration ?
From www.cisco.com/go/fn I see support for several ISDN features for the first image you have listed.
Hope to help
Giuseppe

Hello Ashish,
a key info is missing:
what IP address is on the remote and what ISDN number to use to reach it.
I type an example:
int BRi0
dialer map ip 172.16.5.89 01141377441
no isdn point-to-point-setup
!
You may need to add the broadcast option to support multicast traffic in the dialer map ip command.
Then I would configure the default static route with the IP address of the remote router
ip route 0.0.0.0 0.0.0.0 172.16.5.89
no ip route 0.0.0.0 0.0.0.0 BRI0
the BRI0 is spoofed up.
In DDR you need to provide a reason for making a call and you need to provide an exact mapping of IP address to E.164 number.
In real world scenario the interesting traffic has to be defined carefully for call charges.
I would define as interesting the traffic to the servers using the specific TCP ports.
on the remote router a return static route is needed for the LAN subnet of the 876.
Hope to help
Giuseppe
