Hi

1. What is the line access code for tie line and ISDN.

2. Through tie line just 4 digit dialing is enough

3. Through ISDN you need to dial full digits.

4. For example if you configure 9 as closed numbering plan length 4 digits, call can go through tie line, during route advance the same call cannot go through ISDN.

5. I think you have to give them two access codes 9 and 0 for tie and ISDN respectively.
