Re: [cisco-voip] CUCM SIP Early Attended Transfers
Thanks guys. Nick, that's kind of the conclusion I was leaning towards, and now I have confirmation bias. ;) I'll take a look at that flex reach doc as soon as I can. Also, Brian, I do have an Annunciator in the MRGL of the SIP trunk. Thanks again.

Re: [cisco-voip] CUCM SIP Early Attended Transfers
My experience is that it isn't going to give ringback to PSTN phone A (step 7) when going back through a CUBE without forcing MTP. This was called out as a caveat in the SIP integration guide for AT&T flex reach via CUBE. https://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise/interoperability-portal/flexible-reach.pdf On Mon, Apr 25, 2016 at 1:59 PM, Anthony Holloway < avholloway+cisco-v...@gmail.com> wrote: > All, > > Does anyone have any experience with CUCM, SIP Phones, SIP Trunks, and > early attended transfers (AKA hitting the transfer button a second time > quickly)?

Re: [cisco-voip] CUCM SIP Early Attended Transfers
CUCM pulls in an annunciator for ringback during blind transfers. Make sure the SIP Trunk MRGL has access to an annunciator.
