Hi there, As far as I understood from the documentation, when action application redirect is invoked, the REFER method is implemented. Recently I signed up for a VoIP service and realized that the provider only supports redirection by implementing the UPDATE method. I want to redirect incoming calls requesting specific DIDs to other FS box in a different network (not behind the FS receiving the original INVITE). Perform the redirection by answering the call and bridging it to the other FS box will result in resource wasting and probably call quality degradation (and actually it will be transfer not redirect). So, is there any way to use UPDATE instead of REFER to accomplish redirection for requests received through specific gateway? Thanks in advance. Pablo
