siemens hipath 4000: Busy indication in progress msg 2

[AntBan]

Hi,
I have the following topology:

DigitalPhone---SiemensHipath---Qsig---CiscoGW---MGCP---CiscoCallManager---SCCP---VG224---AnalogPhone.

Call back works fine on Analog phone when called phone connected to Call manager. But this doesn't work when called Phone (busy state) connected to Siemens Hipath.

I see the difference is in the message being sent back to VG224 from Call Manager and Siemens Hipath... Call Manager sends Disconnect (Busy) where as Siemens sends Progress (Busy) which VG224 could not understand.
Can someone help me how to configure Siemens so that it can send Disconnect (Busy) instead of Progress(Busy).

Thanks

You can't really configure that. You could try different QSIG protocols in TDCSU protvar, but you might lose other features.

Progress Busy is a valid message. You should pursue the VG224 maintainer for a driver that behaves according to QSIG spec.

This is an ongoing issue with the Cisco equipment. Perhaps the following link will be some help...
