Help to create sip.conf

Hi, i decide run asterisk read manul and create sip.conf file [code][root@centos ~]# cat /etc/asterisk/sip.conf

[general]

bindport=5060
bindaddr=0.0.0.0
srvlookup=yes

[1000]
type=friend
context=phones
host=192.168.0.25
[/code]
but asterisk give me mistake:

centos*CLI> sip reload Reloading SIP == Parsing '/etc/asterisk/sip.conf': Found == Parsing '/etc/asterisk/users.conf': Found [Jun 16 15:09:27] ERROR[1183]: netsock2.c:269 ast_sockaddr_resolve: getaddrinfo("centos", "(null)", ...): Name or service not known [Jun 16 15:09:27] WARNING[1183]: acl.c:833 resolve_first: Unable to lookup 'centos' == Using SIP CoS mark 4 == Parsing '/etc/asterisk/sip_notify.conf': Found

There is nothing in the file that would explain the error. Where is “centos” used. My guess is that you have a host name with no corresponding IP address.

[root@centos ~]# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=centos GATEWAY=192.168.0.2

here is ping

[root@centos ~]# ping centos PING centos.euroterminal.local (192.168.0.115) 56(84) bytes of data. 64 bytes from centos.euroterminal.local (192.168.0.115): icmp_seq=1 ttl=64 time=0.026 ms 64 bytes from centos.euroterminal.local (192.168.0.115): icmp_seq=2 ttl=64 time=0.019 ms

I decided what problem, but now then i reload asterisk core reload i received[Jun 16 16:55:11] WARNING[1182]: pbx_dundi.c:4835 set_config: Unable to look up host 'a-'

The problem decides, how to close topic?
