1. Brekeke Product Name and version:Brekeke SIP Server 2.4.7.3/286.1

2. Java Version: 1.6.0_20

3. OS type and the version:Ubuntu 10.04.2 LTS , Kernel 2.6.32-28-generic-pae

4. UA (phone), gateway or other hardware/software involved:We are using Cisco 7925 phones that are connected to Cisco Unified CM version 8.5.1.11900-21
The Cisco Unified CM has SIP trunks to our Avaya Session Manager 6.1

We are routing calls from the Cisco CM to Brekeke via the Avaya Session Manager

6. Your problem:So in short we are able to call from another registered client on Brekeke to Responder 5 devices with no issues. We can also call our x-lite4 soft clients from the Cisco phones with no issues as well. However we are unable to connect via our Cisco phones to the responder 5 devices. All sip traces show that we do not get an acknowledgment back from our sip invites.

Enable MTP (Media Termination Point Required) in the Call Manager's SIP Trunk configuration.
