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.
Thanks
John Tafasi
