Hello!

I have a PABX A with 5 LIM. At LIM 3, there are one E&M trunk to the PABX B and one E1 trunk with the PABX C. Through the E&M trunk, the PABX B can connect to any PABX D, E or F with E&M trunks at LIM 1, 2, 4 or 5. But when the PABX B want to connect to PABX C, the call is not complete. When I changed the trunk's PABX B to another LIM, for example LIM 4, the PABX B can connect to PABX C.
What is not working in LIM 3? Can it be a switching failure between analog trunk and digital trunk at LIM 3? How can I fix it?
Thanks guys!
