How is B forwarding the call to C? Is the UAC generating a 300 code to
be returned or is the forwarding handled by ser (ie. storing an AVP for
B and then using avp_pushto() when the initial invite comes in)?

Hello,
I have made some test with cisco ip phone & blind transfer and I have a
question.
Example:
A: a(a)toto.com <mailto:a@toto.com>
B: b(a)toto.com
C: c(a)toto.com
M: mobile(a)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(a)toto.com <mailto:b@toto.com>
To: a(a)toto.com <mailto:a@toto.com>
Refer-To: mobile(a)toto.com
Referred-By: b(a)toto.com <mailto:b@toto.com>
And then when A sends the Invite to the gateways:
INVITE…
From: a(a)toto.com <mailto:a@toto.com>
To: mobile(a)toto.com <mailto:mobile@toto.com>
Referred-By: b(a)toto.com <mailto: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
