[SR-Users] Unsuccessful call using DRouting - Request Timeout

Dears, I started my lab on VMware (debian lenny) where I installed Kamailio 3.2 and started drouting configuration. I'm using 2 PCs each having an x-lite softphone and the Kamailio on the vmware all connected locally. My primary test is to make a call from x-lite on PC (192.168.111.11) to x-lite on PC (192.168.111.226) through Kamailio\ drouting modules (192.168.111.139). What is happening is that when I call 9611558800, for example, am getting 'Calling' message on PC x-lite followed by 'Call Failed: Request Timeout' after a certain time. Attached is my routing logic script, and ngrep for the call that is failing. And my dr_tables data is : dr_rules: 4, '0', '9611', '', 0, '', '#3', 'Lebanon Fix' dr_gw_lists: 3, '5', 'Test Call' dr_groups: 3, '.*', '.*', 0, 'Everyone' dr_gateways: 5, 1, '192.168.111.226', 0, '', '', 2, 'PC1' I tried adding port number to the gateways, remove '#' and add 5 in the dr_rules, remove the "0" from do_routing in the script, but with no success. Reading some related documents and books, I found that all scenarios using drouting have gateways as media servers (Asterisks) . So my question: is this a must, to have a media proxy even using my above primary enviroment? If not, can you please help me finding my mistake that prohibit the call's success(ringing)? Thanks in advance. F.Chahrour
