cisco isdn problems

hi I'm trying to establish a point to point Isdn connection , between two remote sites.

From the center router I'm able to connect to different sites .

I even tried to attach an AT command string to the dialer , to reduce the Channel speed to 56k as follows :

chat-script isdn "" "atq1e0" OK "at&n38&w&y" int dialer 4 dialer string xxxxx modem-script isdn

the central site is Tel Aviv and the remote is NY USA.

does any one have any idea ? I've attached configuration and log from the USA site router. Thank's Ahiya zadok

To resolve speed mismatch issues, configure the call for 56K using one of these methods.

For dialer profiles:

maui-soho-01(config)#interface Dialer1 maui-soho-01(config-if)#dialer string 81560 class 56k !---Dial 81560 and use the map-class named 56K (defined below). maui-soho-01(config-if)#exit maui-soho-01(config)#map-class dialer 56k !---The map-class named 56K that was used with the dialer string is int Dialer1. maui-soho-01(config-map-clas)#dialer isdn speed 56 !---Set the speed of the call to 56K (default is 64k).

For Legacy Dial-on-Demand Routing (DDR) (dialer maps):

maui-soho-01(config)#interface bri 0 maui-soho-01(config-if)#dialer map ip 10.1.1.1 name maui-nas-08 speed

56 81560 !---The keyword speed 56 sets the outgoing call rate at 56K.

Configure the ISDN SPID1 & ISDN SPID2 commands with LDN on the USA router and try.
