Hi all, I'm hoping that some of you clever folk may be able to help me out with a REFER problem I'm facing. If I originate a call from FreeSWITCH to an IVR, and the IVR attempts to transfer the call to another destination using REFER, FreeSWITCH fails with a 403 Forbidden error and reports 'Cannot Blind Transfer 1 Legged calls' in the log. FreeSWITCH is quite correct that there is only one leg of course but should it not be possible for an INVITE to be sent to the address in the Refer-To header anyway? This scenario seems more or less the same as the first 'basic transfer' example in RFC5589 so I think it should be possible unless I am missing something obvious. Are there any special configuration options needed to make this work? I tried setting proxy-refer but it didn't make any difference.
