[SIPForum-discussion] RFC 3655 question for Record-Route?

[kunal lodha]

Hello,

So record-route is just inserted for billing purpose. Is that header not necessary for the proxy to know about the source/destination for routing SIP messages?

Thanks for your response,
KL

Hi,
 
The SIP proxy just routes the SIP messages, so when the SIP proxy receives a message, depending on its role, it can decide if it wants to insert the record-route to header field. If it inserts the record-route,  the following SIP messages will be passed through it.

In this case, may be the Proxy2 is not used for billing, so it don't care about the BYE message. Thus it does not insert record-route here.

Hello,

RFC 3665, last line of page 45 mentions that(Also note that Proxy 2 does not Record-Route in this call flow.)


I am not following why the Proxy2 doesnot Record-Route here. 
Also, how BOB reaches to the Proxy if RR is not included in the INVITE?

Thanks,

KL
