Genesys Cloud - Developer Community!

Hi,

Scenario:

1. Customer calls over PureCloud voice line
2. In architect we transfer to number ( over a BYOC SIP trunk)
3. 3rd party does its thing, adds data on UUI Data and/or SIP Customer headers
4. 3rd party ends call and sends REFER back to Genesys
5. Via a POST-Flow we go to 2nd architect flow.
6. Using Get SIP Headers (or getting RAW SIP headers) we try to get the Customer data, and/or
7. using the Call.UUIData attribute, we try to read the UUIData, (but always retruns empty)

I try to retrieve the UUI data (or custom SIP headers after i do Transfer to Number.

We see that the data is on the SIP REFER Message:

Any help on how to retrieve this data from a REFER action would be greatly appreciated !

Hi,
there is a good article: https://developer.genesys.cloud/blog/2021-09-03-transferring-calls-to-external-using-byoc/#sending-data-from-your-external-device-to-genesys-cloud-on-take-back-and-transfer

Basically the UUI data needs to be added to the Refer-To header like this:
Refer-To: <sip:address@ip?User-to-User=XXhexdata%3Bencoding%3Dhex>

From experience custom SIP headers will not be available in Architect when a REFER aoccurs.

Thanks Christian,

We got it to work.

All in all it seems very weird to use this Refer-To field, and not User-to-User header field but if that's what it takes.

Thanks for your help.
