Hello, 
could anybody can explain me why the progress indicator has been set to "forbidden" in the setup message? (H.225v4 §7.3.10)

when H.323 is used in VoIP trunking between 2 ISUP networks, the lack of this information has an impact on the selection of the called ISDN terminal (for exemple : if a fax and a telephone are behind a PABX and if BC=3.1kHz, without the progress indicator, fax terminal can pick up the call instead of the telephone)

Thank you.
