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=20
