How to have SBC send Request URI as @hostname instead of @ip for SAG

@1

Hi folks,

 

I have a SAG, e.g.

 

session-group

group-name         cisco.com

dest                    1.1.1.1

                          1.1.1.2

 

and two session-agents, e.g.

session-agent

hostname            1.1.1.1

ip-address            1.1.1.1

 

session-agent     

hostname            1.1.1.2

ip-address            1.1.1.2

 

Now I find out when the INVITE sent out from SBC, the Request URI in INVITE is @1.1.1.1 instead of @cisco.com, how can I have SBC send INVITE to 1.1.1.1 or 1.1.1.2 with @cisco.com in Request-URI, To, etc.?

 

Regards,
