Hello Everyone, I am working with a J4BRI and it works ok with our national provider ( TelecomItalia ) and when connected to ISDN pabx ( Ericsson and Tenovis ). We now have switch to a new telco provider ( Fastweb ) which brings you S0 via Cisco 1760 VIC-2BRI interface. They say ( and Cisco says ) that VIC-2BRI emulate perfectly the national isdn standard, but I found that it is not true. First of all I have to switch 3-4 and 5-6 pin of the isdn cable, otherways is not going to work, not too bad but anyway... The critical thing is that I can not receive calls! The normal ( telco and pabx ) Q931 SETUP message arrives like this: 08 01 2c 05 a1 04 03 80 90 a3 where: 08 means Q931 message 01 length of call reference field 2c call reference field a1 sending complete 04 next is bearer cap 03 80 90 is bearer cap and so on when I connect the J4BRI to the VIC-2BRI I receive 08 01 2f 05 04 03 80 90 a3 ....... a1 so the a1 ( sending complete ) arrives at the end of the SETUP message. After the bearer cap , the calling number and the called number. Asterisk does not recognize this byte stream as a SETUP message and so discards it. Is there anything I can do or is a developer problem? -------------- next part -------------- An HTML attachment was scrubbed...
