ROUTE header - is used incase of source UA want to send SIP
Method(Messages) to Destination UA through Proxy(Ex :
A(Route:Proxy1,Proxy2)->Proxy1->Proxy1->B)

RECORD-ROUTE Header -is used if any proxy or IP node want to included in
Call flow for Future SIP REQUESTs the Proxy will add his address in
Record-Route.

Ex :
A(Route:Proxy1,Proxy2)->Proxy1(Route:Proxy2;Record-Route:Proxy1)->Proxy2(Record-Route:Proxy1)->B
-Here Only Proxy1 want to include in future sip request .. so Proxy2 will
not add
.

Thanks,
Karthik.
