HI,

I'm trying to setup a client PBX to register to our A2billing server, and i keep getting 403 forbidden (bad auth) back from A2billing.

I have checked the username & secret and these are correct. I've recreated the VOIP account as well; still no joy. The PBX is IPFX director; i know i can register this PBX to A2billing because i've done it with another install.

There is no NAT occurring, my VOIP settings from the account has NAT=NO. I have verified the account works by registering to it with VOIPER from the same network as the IPFX server. I'm just not sure what setting is tripping me up with the IPFX registration; there's not much i can configure on teh IPFX server; just username, password, and IP of SIP server.

I cannot upload files for some reason, so i'll post a going with the A2billing log, not sure how i can get the wireshark from the IPFX server up.

We are running A2Billing 1.9.4 Hope someone can assist.

Thanks.
Adam

Heres the relevant log of teh failed authentication:
