[Serusers] Billing and Blind call transfer

[Schweizer Laurent]

Hello,

I have made some test with cisco ip phone & blind transfer and I have a
question.

 

Example:

A: a at toto.com

B: b at toto.com

C: c at toto.com

M: mobile at 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 at toto.com

To: a at toto.com

Refer-To: mobile at toto.com

Referred-By: b at toto.com

 

And then when A sends the Invite to the gateways:

 

INVITE.

From: a at toto.com

To: mobile at toto.com

Referred-By: b at 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
