ACSE Make Association message for OXO

[dcoup]

I need to send an ACSE Make Association message to an Alcatel OXO and tell it that I want to use CSTA phase 2. The message I'm sending is below, but the PBX is rejecting it. What am I doing wrong?

Code: Select all

/-- message 1 --/
ACSE-apdu {
    aarq {
        aSO-context-name = 1.3.12.0.180.1        
        user-information {
            EXTERNAL {
                direct-reference = 1.3.12.0.218.200                
                encoding {
                    single-ASN1-type {
                        ACSEUserInformationForCSTA {
                            cSTAVersion = 01000                            
                            cSTAFunctionsRequiredByApplication {
                            }
                            cSTAFunctionsThatCanBeSupplied {
                            }
                        }
                    }
                }
            }
        }
    }
}

Hello dcoup,

Oxe can do only phase 1 as I remember.

I think the OXE is compatible with the 4400, which is a phase 2 PBX. Our customers who use Alcatel can send the same ACSE Make Association message to an OXE that is sent to a 4400, and they can exchange phase 2 messages without problems from that point.

But the OXO apparently isn't compatible with the 4400; the same ACSE Make Association message doesn't work. Perhaps the OXO does only use phase 1.

CSTA ph I supported by OXO like hans-juergen stated.

Hi, below in a bit different format what works well on OXO.

)


Hop this will help.
