ISDN tip wanted

Thu Oct 31 13:58:08 UTC 2002

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 
André
