Hello everyone,
CUCM v11.5 does not use the REFER method in SIP to transfer a call. It uses INVITE and UPDATE messages. This causes extra SIP communication legs in UCCX transfer "call redirect" scenario.
I would like to know if it's posible to solve this behavior using a CUBE, where the cube should detect a transfer and consume Reinvite message and replace it with refer method.
Thanks in advance
