>>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.
