Hello Community,
I am trying to create a call flow PSTN -> SBC (invite) -> GVP(Refer) -> SBC, i am using composer to create the flow in GVP to transfer the call to SBC using a customer variable and setting it as target in transfer block, in the same transfer block when i am selecting the call transfer options as below but GVP is not sending a Refer and seeing below error
Transfer options :

Error see in SIP logs when request a refer
13:01:02.257 SIPCONN(MSML_Service): REFER - execute sst.
13:01:02.257 SIPCONN(MSML_Service): REFER rejected, error 10000000
Any open suggestions on how to configure the GVP to send the refer request instead of INVITE
