[sip-comm-dev] hi,gentlemen and ladies, can i ask a question about attended transfer


#1

i want to implement the function of the attended transfer
but failed though after a lot of hard works
  
i know there's the unattended transfer in the project implemented by the method transfer in class OperationSetBasicTelephonySipImpl
  
what i wonder is how to implement the attended transfer, is it to add replaces parameter into the Refer-To header or a independent replaces header in another Invite request, can you instruct me of these things if there're some codes it'll be greatest...
  
thanks a lot..
regards
dracularking

Hello dracularking,

Attended transfer is actually already implemented in SIP Communicator.
You are simply expected to establish 2 simultaneous calls and then
transfer on to the other.

Hope this helps
Emil

Boys and girls interested in attended call transfer,

r4584 introduces support for the feature in question
(OperationSetBasicTelephonySipImpl#transfer(CallParticipant,
CallParticipant)). Please give it a spin so that problems can be
uncovered and report them with steps to reproduce, logs and tcpdumps
(if applicable). As Emil said, the attended version will be used when
the transfer target is already participating in a call.

Thanks,
Lubo
