[Serusers] I have a problem trying use SIP

My friend, First I thank you for reading this e-mail and being interesting on my problem, I have SIP 0.8.10 installed in my Red Hat 7.2,, it was easy to install and configure the packages but after it all I’m not getting to connect to my SIP server. If I type the command “ser” I can see this message bellow: [root@afs sbin]# ser Listening on 127.0.0.1 [127.0.0.1]::5060 192.168.0.17 [192.168.0.17]::5060 Aliases: afs:5060 afs.advus.com:5060 localhost:5060 But when I try to check the port typing the command (telnet afs.advus.com 5060) just to prove the port 5060 is on the listening status and i just do not get any connection. I do not have a firewall installed on this machine and I m trying to connect inside my site, I mean, I am trying to connect inside my network not on the internet. I realy need to have the SIP server working, but I already did everything I knew to make it just works fine but as in all my trying I fail.
