[Serusers] Using IP address as domain

[mukesh]

Hi friends,
	I have SER (with database support) running on my linux box. But I do
not have a domain name registered for the IP of this machine but it does
have a public IP (202.87.xx.xxx) address which allows me access it from
outside.

	If I try to access (using sipsak client) a uri from local system it
fails.
	example URIs  I am trying are ...
	sip:mukesh@<public ip>
	sip:mukesh@<public ip>:5060 

	...with no result :(
	
	I referred http://mit.edu/sip/sip.edu/ser.shtml to configure my
ser.cfg. 
	
	So the question is How can I connect to SER using IP and do I need
to use "# export SIP_DOMAIN=<public ip>"?	

Regards
Mukesh
