[SIPForum-discussion] strict and loose routing differences

[Sumeetkumar Bhardwaj]

Hello,

In strict routing , Request-URI is overwritten. The Request-URI always contained URI of the next hop (which can be either next proxy server which inserted Record-Route header field or destination user agent). Because of that it is necessary to save the original Request-URI as the last Route header field.

In Loose routing ,the Request-URI is no more overwritten, it always contains URI of the destination user agent. If there are any Route header field in a message, than the message is sent to the URI from the topmost Route header field.
 
Thanks,
Sumeet
