Hi! I am from India, we have a SIP server in USA which use to register on prefixes of 4 digit like if you want to call a no. 12127773456 then the sip message will look like 524112127773456(a)202.66.135.55, where 5241 is the 4 digit prefix for authentication. Now I want to have a SIP proxy server at our end it self and it will redirect the uri to the destination gateway. How to do that? Any body have the configuration file for this configuration?
