blocking call waiting from TL11

[serg75]

May I disable Call Waiting Tone to busy extension (fax) when call comes from external line? If I try to set SERV=02001200 then it working fine with public ISDN but not with analogue CO (TL11). What I should do to prevent beeps while fax is working and somebody call through TL11? System is BC10.
Thanks for aswers.

Hi
Change the first bit on SERV on TL11 route to zero.
This should stop call waiting.

Hi LME.
Yes, it method will work - if I set this SERV in all routes. But my purpose is disabling receiving of Call Waiting tone for some extensions and reserving this tone for all other extensions.
