Warnings and Errors when registering sip

Hello Everyone,
Trying to register sip but I get the following error and warnings after “sip reload” in the asterisk console

This is the content of my sip.conf file:

Can anyone help me please? Will really appreciate it.

Does the hostname of the machine itself resolve? According to the output it doesn’t appear to which can cause problems not just for Asterisk but other applications. An explicit entry is usually placed in /etc/hosts so that resolution does not depend on an outside DNS server.

hi jcolp
I’ve ignored the error and warning and configured “host” in sip.conf with static IPs and now the peers are reachable.
Can sip be configured with static IPs

Thanks

I don’t understand what you mean by configured. You can specify host entries in sip.conf with static IPs as you’ve done. That doesn’t change the fact your system can’t resolve its own name though.

hi,
why is it that when I register my ekiga softphone on my centos with the IP of my asterisk server is says cannot register but when I use my IP gateway it rather registers easily

Without understanding the network topology, where things are, and how it is setup I don’t think anyone could answer that with certainty.
