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"

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
Transfer Mode = Circuit
Transfer Rate = Packet - not specified
Channel ID i = 0xAC
Exclusive, Channel 52
Facility i = 0x91AA06800100820100A129020200B106042B0C0928301DA0078005343534373380053435353131400504038090A38C01008D01FF
Calling Party Number i = 0x0081, '45473'
Plan:Unknown, Type:Unknown
Called Party Number i = 0x80, '45511'

and Alcatel send

Channel ID i = 0xA8
Exclusive, Channel 64
CCM is sending the Invalid information element, because Alcatel sends A8 instead of AC.
