Hello Everyone:

Can someone explain these two routing scenarios of SIP calls for me.  

1.  The first would be SIP1 calls SIP2 and neither party has moved.  In this
example, how does SIP1 find SIP2?   What are the roles of proxy servers,
enum, and location servers?

2.  The second would be SIP1 calls SIP2 but SIP2 has moved.  In this
example, how does SIP1 find SIP2?  What are the roles of the proxy servers,
enum and location servers.  The location servers would be required in this
example.  Will the routing be dynamic?  For example:  normally I work at
Illuminet but today I go to client's office for a meeting and plug in my SIP
device into their proxy.  How would a call for me be routed to the Client's
office?

Also, would the ENUM proposed databases be involved in the routing for
either scenario?  

Sincerely,

Kevin McCandless
