[asterisk-users] RFC about SIP 'To' header after call diversion?

[Benoit Panizzon]

Hi List

I'm struggling to find the correct RFC which "exactly" defines how a SIP
Invite has to look like after a call has been diverted.

Especially what the content of the To: header field has to be.

Example call flow:

Alice calls Bob who diverts to Carol.

Alice => Bob

Invite: bob at example.com
From: alice at example.com
To: bob at example.com

Bob => Carol

Invite: carol at example.com
From: alice at example.com
To: bob at example.com <= is this correct, or should that be carol?
Diversion: bob at example.com

Mit freundlichen Grüssen
