[Serusers] More call transfer questions

[Steve Blair]

  I'm a bit stuck and wonder if someone on this list can help.
When a call arrives at a Cisco IP phone registered to our
SER proxy from the PSTN it is answered. The called party
then tries to transfer the call. In either case a new invite is
generated. I'm under the impression a refer message should be
generated but given the way attended transfer works on the
7960s it doesn't seem possible to have a refer generated. Has
anyone else seen this? If so any thoughts on what is happening?

Thanks,Steve
