HI All
I am currently working on a project were we will be using the UUI functionality using Refer and I would like to find if anyone using purecloud has managed to get this working ?
The setup is receive a call into purecloud, I then redirect the call over a sip trunk configured on PureCloud to a 3rd party, they deal with the call and if they need to return they do so by sending the call back down the trunk using the "Refer" method. We have tried multiple options but cannot get this to work.
For testing we added "1234|Additional Services|CLI" into a user-user header using the ascii format, I can confirm that we were able to see the call and Parse the data in Purecloud. The issue is when using "REFER". Details below
(User-To-User: 00;encoding=ascii;purpose=isdn-uui;content=
67911981-3728220801-882359@MSXXX.telecom.com)
The issue that we are currently having is when the UUI information is populated using the Refer Method Architect does not read this, therefore we are not able to use this data. You will see the data is being passed by the sip trunk however Purecloud does not read this data.

We have been instructed to try adding the information to the Refer-To Field as highlighted above, however when the call is returned by the 3rd party down the SIP Trunk the calls goes silent and does not route into the call flow. By adding this string it breaks the return call, we are trying to find away that we can get this UUI data into Architect using Refer as the 3rd party needs to drop out of the Media path.
