Hello,
I have made some test with cisco ip phone & blind transfer and I have a question.
Example:
A: a@toto.com
B: b@toto.com
C: c@toto.com
M: mobile@toto.com
A calls B but B forward the call to C, C answer the call and transfer the call to a mobile phone M via a pstn gateway.
When C sends the REFER request to A we have something like this:
REFER.
From: b@toto.com
To: a@toto.com
Refer-To: mobile@toto.com
Referred-By: b@toto.com
And then when A sends the Invite to the gateways:
INVITE.
From: a@toto.com
To: mobile@toto.com
Referred-By: b@toto.com
But the call is transferred by C and not by B so the Referred-By: is not correct. Is that an error from the cisco ip phone (I think not) and how can I bill this call (I do the billing on the gateways).
Thanks.
Laurent
