Hi, I'm trying to establish an ISDN call between Switzerland and New-York. The
destination is in New-York, ISDN line provided by Verizon. The called is disconnected just after being set up (see NY-router log below), and the problem seems to be that Verizon switch does not understand the callref flag (0x01 and 0x81) correctly.
The funny thing is that i have another router in NY, another ISDN line
from Verizon, and i'm calling from the same number in CH and it works perfectly...
Does anyone have a hint for me ? Thanks Andr?
