Hello
isdn callback does not require isdn caller ,it adds more security to your dial system.If you remove this command,and add ppp callbak request on your calling router and ppp callback accept on your called router,I think it is all ok.A few days I just test the ISDN callbck.Addtionally,you can see the cause of your isdn call failure:
4d19h: ISDN BR0: Incoming call rejected due to screening!!!! it is because you configure isdn caller on your called router.
