Hi,
I am transferring an old FreePBX to a new server. I have installed the latest FreePBX distro on a VM under KVM running on a RHEL7 box. I have used PCI passthrough to pass the two B100e BRI cards through the VM. I understand the issues with zaphfc and have tried many options - downloading and compiling from the openvox site, downgrading dahdi, etc. But I keep having the same issue.
Incoming calls are working fine and all the local sip handsets are fine, but I can’t get any outgoing calls to work:
– Requested transfer capability: 0x00 - SPEECH
– Called DAHDI/g0/0123456789
– Span 1: Channel 0/1 got hangup, cause 27
– DAHDI/i1/0123456789-4 is circuit-busy
– Hungup ‘DAHDI/i1/0123456789-4’
== Everyone is busy/congested at this time (1:0/1/0)
Once I got the drivers installed FreePBX found the cards and I could configure them using the web config frontend:
