[SIPForum-discussion] how to transfer a call use sip

[Srinivas.Pratapa]

Hey Dan,
We've been trying to get transfer working over SIP. We are using
Bandwidth.com as our provider which in turn uses level3 for their
infrastructure. Do you happen to have any documentation on how the
transfer request should be sent? We are trying this transfer using VXML
constructs and none of the approaches (using consult/blind/bridge) seem
to work.
thanks
Srinivas

To handle a transfer in our network we usually see an re-invite..
 
Liurf...if you want a sip ladder let me know I will put one together for
you.

And do not forget that REFER is just a component in the process
described in

	Best place to start would be the following draft that lists the
call flow and example message contents:
	
http://ietf.org/internet-drafts/draft-ietf-sipping-service-examples-10.t
xt
	Then refer the RFC 3515 (REFER method)
