Subject: ISDN callback problem
> Hi Group,
>
> I have tow routers r2 and r5 connected through ISDN simulator. r2 is
> configured as callback client and r5 as callback server. I am having
problems
> getting r5 to callback r2. I have included the output of "debug isdn q931"
for
> both routers. It looks to me that it is a timing problem between the two
> routers. Could some one find out what is wrong with this configuration.
