Resolution
This
feature is implemented in Cisco IOS Software Release 12.4(2) onwards.
Once Cisco IOS is upgraded to anything later than 12.4(2)T, you can do
this configuration:
#configure terminal
(config)#voice service voip
(conf-voip-serv)#sip
(conf-serv-sip)#[no | default] localhost dns:
Example:
(conf-serv-sip)#localhost dns:name1.com
In order to disable the usage of DNS name under specific dial-peers, you can configure the dial-peer with:
#configure terminal
(config) dial-peer voice 100 voip
(config-dial-peer)#[no | default] voice-class sip localhost
[dns]:
In
the CLI, there is a provision to exclude a specific dialpeer from the
use of the global configuration under voice service voip. In order to do
that, use the no version command under dialpeer. This change has been
made to allow for the case when the global localhost command is
configured and most but not all the dialpeers want to use that config.
For the dialpeers that want to fallback to the use of the IP address in
the From, Call-ID & RPID headers, this command can be useful.The
default version of the command causes the dial-peer to use the globally
configured CLI under voice service voip, SIP.
Example:
dial-peer voice 6 voip
no voice-class sip localhost
