ISDN PRI problem

[naive.naive]

When the dialing router initiate to the receiving router, it gives an error message below at the receiving router end:

*Jan 13 09:09:41.522: ISDN Se1/0:15 Q931: RX <- SETUP pd = 8 callref = 0x00E0

Sending Complete

Cause i = 0x8095 - Call rejected

Whats does that means??

Hello,

most likely, there is a problem with the dialer interface bound to a physicall interface. Check if the physical interfaces have the command 'dialer pool-member' configured, and the corresponding dialer interfaces the 'dialer pool', as in this example:

interface BRI0/0

dialer pool-member 1

!

interface Dialer1

dialer pool 1

GP

The receiving router dialer config as below.(the router will be accepting calls from 2 remote site)

interface Serial1/0:15

no ip address

encapsulation ppp

dialer pool-member 1

isdn switch-type primary-net5

ppp multilink

!

interface Dialer1

ip address 1.188.8.2 255.255.255.248

encapsulation ppp

dialer pool 1

dialer idle-timeout 60

dialer load-threshold 1 outbound

dialer-group 1

ppp authentication chap

!

interface Dialer2

ip address 1.188.8.2 255.255.255.248

encapsulation ppp

dialer pool 1

dialer idle-timeout 60

dialer load-threshold 1 outbound

dialer-group 1

ppp authentication chap

Hello,

on your dialer interfaces, you need to specify the remote name of the device calling in, e.g.:

interface Dialer1

ip address 1.x.x.x.255.255.248

encapsulation ppp

dialer pool 1

dialer remote-name Branch_Router

dialer idle-timeout 60

dialer load-threshold 1 outbound

dialer-group 1

ppp authentication chap

Also, make sure that the local username and password are configured:

username Branch_Router password 0 cisco

On the branch router, you need to do the same, with the username being the name of the central router. The passwords need to match, and are case- sensitive:

So, if your central office router´s hostname is ´Central_Router´, the following needs to be configured on the branch router:

Branch_Router

!

username Central_Router password 0 cisco

HTH,

i've tried, it's the same error..

i'm just wondering is there any error on my dialer config?? coz its sharing same dialer pool ??

[Georg Pauwen]

Hello,

at second glance, I would say yes: the IP addresses on both dialer interfaces are identical, you might want to change those...

HTH,

GP

[naive.naive]

have tried to change the IP address..its the same result..

but i've tried something else..

i removed dialer pool 1 and dialer-group 1 in the int dialer 2..and it managed to dialed in but cannot be bind to a dialer...

any idea what is configured wrongly??

[Georg Pauwen]

Hello,

have you configured the ´dialer remote-name´ on the dialer interfaces ?

Regards,

GP

[naive.naive]

yup..i've entered the dialer remote name..but still the same...

anything that i configured wrongly??

Hi,

What's missing from your config is the "ppp authentication chap" command on the D-channel of your PRI ie. Serial 1/0:15.

Then add the "dialer remote-name " on the dialer interfaces.

That should solve your problem.

Pls rate this post if it helps.

nbhandarker,

thank you..

you are my hero..

you solved my problem..

but how can i rate it??
