UDP <-> TCP for OCS 2007 R2

[johnc]

1. Brekeke Product Name and version:
2.3.7.4

2. Java version:

3. OS type and the version:
Windows 2003 Server Standard Service Pack 2

4. UA (phone), gateway or other hardware/software involved:
Sip Gateway

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
None

6. Your problem:
I'm evaluating the product to see if it's going to work for our situation.
I don't know much about this stuff so bear with me.

We're implementing OCS 2007 R2 and our Sip Gateway can only send UDP. They gave us two ip addresses, one for outgoing calls and one for incomming calls, both over UDP.
As OCS 2007 R2 can only listen on one IP address and uses native Sip Trunk over TCP I need a middle software which can just take the UDP ip addresses and forward them to one ip over TCP.

I'm having prblems finding the right settings for the PBX for this. I search the forums and most of the info was about setting the OCS ip addresses and not about setting up the forwarding in Brekeke PBX.

Can someone please point me in the right direction and let me know if this is the right solution?

Thanks,
John

from the link http://wiki.brekeke.com/wiki/Configure- ... BX-for-OCS

maybe you need to combine the Rule-1: From OCS to PBX and Rule-2: From PBX to OCS like

[Matching Patterns:]
$addr = Gateway_IP
$request = ^INVITE
To=sip:(.+)@

[Deploy Patterns:]
$transport = TCP
$auth = false
&net.sip.transport.follow.request = true
To = sip:+%1@OCS_IP
