> Inside Asterisk2 box is installed an HA8 board with a single 4 BRI module.
> When dialing in from phone1 to phone, no call is established and  Asterisk2 shows:

> I've recorded pri intense debug in a file I can send.
> Before filling this issue, I've googled a bit and found nothing either recent or helpful. Please, apologize if I missed anything.
> I can of course, handle configuration details but I must add I got this issue while preparing/testing to upgrade an 3-4 years old system.
