CUCM 10.5 integrated with Alcatel PBX

[Muaaz El Kamali]

Hi,

I trying to integrate with Alcatel PBX over Qsig as I don't have SIP license in Alcatel. My question is callback feature supported over qsig to alcatel pbx?

I am getting this message from the phone "callback cannot be activated on xxxx"

Regards,

[Alexey Platov]

Маке а trace for callback attempt.on Cisco or Alcatel side.

Looks like it is not configured properly for QSIG  as it does not "understand"

FACILITY request.

I got these details.

Cisco is sending 

Oct 30 09:29:02.040: ISDN Se0/0/0:15 Q931: TX -> SETUP pd = 8  callref = 0x0011 
        Sending Complete 
        Bearer Capability i = 0xA880 
                Standard = ISO/IEC 
                Transfer Capability = Unrestricted Digital

        Facility i = 0x91AA06800100820100A129020200B106042B0C0928301DA0078005343534373380053435353131400504038090A38C01008D01FF

                Plan:Unknown, Type:Unknown 
        Called Party Number i = 0x80, '45511' 
                Plan:Unknown, Type:Unknown

and Alcatel send

Oct 30 09:29:02.076: ISDN Se0/0/0:15 Q931: RX <- CALL_PROC pd = 8  callref = 0x8011 
        Channel ID i = 0xA8 
                Exclusive, Channel 64

CCM is sending the Invalid information element, because Alcatel sends A8 instead of AC.

First, which call you try to investigate?

Your first trace shows a CCNR attempt when calling from Alcatel to Cisoc and tje latest one shows a call from Cisco to Alcatel.
