Brekeke SIP Server don`t feedback ACK to SIP Trunk Gateway

1. Brekeke Product Name and version:Brekeke SIP Server 2.1.6.6

2. Java version:1.6.0_05

3. OS type and the version:Windows XP

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

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :Pattern 1 - all on one subnet

6. Your problem:
The SIP Trunk Gateway have E1 port connected to a PBX, and a WAN connected to the same subnet of IAD and SIP server.
There are lots of numbers in PBX, so SIP Trunk Gateway can not register with a only number.
So I add a dial plan indicated the calls to SIP Trunk. In Matching Patterns: $request=^INVITE;$registered=false; In Deploy Patterns:$target=trunk_ip. So that the registered IADs will make calls to each other freely and IAD users can make a call to PBX users.
But I found that the SIP Server doesn`t reply ACK to the 200 OK of SIP Trunk. So the talk will break after 30 seconds.
Could you help me?

Hi

Did you read the document carefully? I think you need to modify your DialPlan rule. For example, you should add "To" definition in your Deploy Patterns.

--------
[Matching Patterns:]
$request = ^INVITE
$registered = false
To = sip:(.+)@

[Deploy Patterns:]
To = %1@target=trunk_ip
--------
