Hello Vaibhav,

check the isdn switch type you have configured with ISDN service provider

Channel ID i = 0x81

Called Party Number i = 0x80, '01244020800'

>>>> Plan:Unknown, Type:Unknown

Jan 6 09:42:53.540: ISDN BR0/0/0 Q921: User RX <- RR sapi=0 tei=66 nr=105

Jan 6 09:42:53.668: ISDN BR0/0/0 Q921: User RX <- INFO sapi=0 tei=66, ns=28 nr=105

Jan 6 09:42:53.668: ISDN BR0/0/0 Q931: SETUP_ACK pd = 8 callref = 0xBE

Channel ID i = 0x89

Jan 6 09:42:53.684: ISDN BR0/0/0 Q921: User RX <- INFO sapi=0 tei=66, ns=29 nr=105

verify if you need to use some prefix digits before the number the router dials

if you like you can post your config

Hope to help

Hello Vaibhav,

I would use the command

dialer map ip

instead of dialer string

dialer map ip 10.10.23.89 name broadcast 01244020800

this allows also to specify the name of the remote router used in authentication.

OR

remove all the dialer strings and leave only one and add

dialer remote-name

I would then use the next-hop in the floating static default route so that a simple ping to a net in the other site can trigger a call

ip route 0.0.0.0 0.0.0.0 10.10.23.89 99

the isdn switch type looks like fine with basic-net3 because isdn layer2 is fine.

But what country are you ?

Hope to help

Giuseppe

Vaibhav, kindly check with service provider if the number which you are dialing to connect to ISDN cloud is servicing or not?
