Hi Guys,
I've taken over a network that has ISDN back-ups to the main routes, everything calls into the main site if the attached serial link goes down.
The company are using callback and I've not seen this before...basically there's a 'ppp callback request' added to the dialer 1 config of the calling router and a 'ppp callback accept' at the main site.
When using the 'isdn test call int bri1/0 <number>' command, some test calls stay on line until I issue the 'disconnect' while others drop after one second. Some of these dropped calls callback while others don't.
Any ideas why this should happen please?
Regards
Peter
