[cisco-voip] PBX to IP-PBX via sip

[Ratko Dodevski]

Hi, I need just a little help :)
I'm trying to connect legacy PBX (via PRI interface) to an IP-PBX (via SIP).
I've tried several configurations but still no call goes through. On the
IP-PBX side i get messages which say that router tries to make a call as
anonymous at ipaddress which is not allowed. Here is my config on the router
side. I should mention that I don't have the actual PBX, i have some tool
which acts as a PBX. Also, need to pass digits without any transformations.
Dial-peer voice 1 pots is the actual number that needs to be reeched.
Any help would be appreciated.
Note: calls should go through SBC... right now it's not there is some direct
communication between VG and IP-PBX. Should the SBC be proxy???
