Ladislav, the problem is ,if I didn't add these two route headers,the application server will do a DNS lookup,which is more than 30 seconds. I also want to make Iptel ser looks like a S-CSCF which defined in 3GPP standard. thanks Fang tian.

As far as I know you don't need to add any route header in this case. On the top of SIP message is VIA header which says which way your application server should answer back..
Route header is used when you have more proxies in the way where the message you want to route through
from RFC 3261:
The Route header field is used to force routing for a request through the listed set of proxies. Examples of the use of the Route header field are in Section 16.12.1.
Example:
Route: <sip:bigbox3.site3.atlanta.com;lr>, <sip:server10.biloxi.com;lr>Can anybody confirm?
