Hello

Can Any body help?
I have a Hipath 3800 and I can receive calls but I'm having trouble making outgoing calls using ISDN trunk. I have two Trunk, External and ISDN, My seizure code for External is 1 and ISDN is 0. I can dial out using External by dialing 0. But when I dial 1 it gives me error. How can I dial out using ISDN trunk?

pls help.

regards
 
Is LCR running? Have you got rules for the alternate access code you are trying to use?
 
Is the trunk up?
Do you have the necessary permissions to dial number?
Can you trace the ISDN call and see what the error is?
If the other end of the ISDN is a phone system, can you trace that end to see what is happening?
 
Sounds like an LCR issue.
Have you got a copy of the KDS?
