Hi guys .. I need your help please... I am trying to setup an FS box. It has to be like a 3 way thing since i reside in one network - my FS machine resides on another network - and my provider (gateway) resides on another network. I am going to try to be specific as much as i can. I did a Quick and Dirty install. Here is my testing servers info. Hardware Intel Dual Core 2.6 GHZ Real memory 3.56 GB total, 267.71 MB used Hard Drives 1 SATA 250GB MotherBoard Biostar P4M900-M4 Motherboard - VIA P4M900, Socket 478, MicroATX Software Operating system CentOS Linux 5.2 Kernel and CPU Linux 2.6.18-92.1.22.el5 on i686 Apache 2.2.3 MySQL 5.0.45 SSH OpenSSH 4.3 freeswitch@internal> version FreeSWITCH Version 1.0.trunk (13181M) Ok the FS testing server resides on xxx.9.10.xxx. The gateway resides on xxx.9.9.xxx. And my computer resides on 75.74.xxx.xxx (My computer has X-lite) installed. When i create the SIP profile on X-Lite in my computer and tell X-Lite to register on xxx.9.10.xxx It says discovering network ... Initializing... Registering ... And then it shows up your Your username is: 1000 (looks like it is registered). Now when i try to dial 5000 to listen at least to the IVR demo i get ... The person you are calling is unavailable please try again ... message. and shows on the top of the username ... Call failed: Request Timeout (message) And on the fs_cli console it shows this .. freeswitch@internal> 2009-04-29 11:46:05 [DEBUG] sofia.c:4242 sofia_handle_sip_i_invite() IP 75.74.xxx.xxx Rejected by acl "domains". Falling back to Digest auth. I am a total noob on this. I replaced my original acl.conf.xml with this... <configuration name="acl.conf" description="Network Lists"> <network-lists> <list name="test1" default="deny"> <node type="allow" cidr="75.74.xxx.0/24"/> </list> </network-lists> </configuration> I shutdown FS and then restart FS with the -nc option. And Still the same thing. My gateway is a CANTATA switch which does not require authentication. I am trying to generate a call from my 75.74.xxx.xxx using X-Lite to a PSTN phone on the outside using the CANTATA switch on xxx.9.9.xxx through my FS box on xxx.9.10.xxx But as for now I can't even get the IVR to work for now ... Since i don't know anything about FS i would like to know what am i doing wrong.. And what files have to be either created or updated to do this. Thanks to everyone for all the help Edward
