Note if the proxy[x].address is set to “localhost”, the W25 will not register to 
any SIP server. 
To display the entries in the call server, use the following command  
cf show ims.callserver 
ims.callserver[0].domain "server.com" 
                 .proxy[0].address "host.server.com" 
                          .port 5060 
                 .outbound_proxy "" 
                 .local_ip_interface "ppp0"           
The domain parameter is for future use. The proxy[x].port is by default 5060 
(according to the SIP standard). The port number only needs to be 
changed in special case. 
In a normal scenario the SIP server is accessible via the WAN interface, 
but for test and demo purposes it’s possible to use a SIP server which is 
connected on the LAN interface. To change this you need to modify 
“local_ip_interface” from “ppp0” (WAN) to “br0” (LAN).
