CTI Server IP and port in UCCX DevNet sandbox env

[dongzhao2024]

Dear Cisco community, 

Do we know what is the IP and port for CTI Server in UCCX DevNet sandbox env? Previously I connected to 10.10.20.20:42027 in PCCE sandbox. Due to PCCE is recently unavailable for reserving, I switch back to UCCX for test. While I can login Jabber and Finesse, I haven't found the related CTI Server address.

I did notice in Jabber Options -> Accounts -> Phone Service, there is a read-only setting of "CTI Server" with value "hq-cuum-pub.abc.inc", which I later found the corresponding default port number is 2748. Some call it "CTI Gateway", but it seems is actually the CTI Manager inside CUUM that utilize JTAPI.

I am trying to find the CTI Server which Finesse is talking to and is using CTI Server protocol defined in https://developer.cisco.com/docs/contact-center-express/#!all-message-types-organized-by-id-number

Appreciate any guidance while I navigating this area. Thanks!

I found it myself:

The UCCX CTI Server locates inside UCCX server, which IP is 10.10.20.10 with port12028. But I still investigating why my CTI client which previous worked correct with PCCE failed connecting UCCX with error `FAILURE_CONF:1 Status = E_CTI_INVALID_FIELD`.

Additional finding regarding this CTI connection error: UCCX sandbox is using version 12.5 which 'The minimum supported version for Unified CCX CTI Protocol is 10. The maximum supported version for Unified CCX CTI Protocol is 18.' My initial CTI client is using version 22 and failed here. After I change version to 18, it shows new error:

FAILURE_CONF:14 Status = E_CTI_NO_ERROR Message = "Unsupported ACMI version18"

ACMI is a variace of GED-188 and I am currently stuck at here.

My code related log:
